  • How to reset Bash on Mac OSX, .bash_profile corrupted and bash no longer works

    - by user1463172
    I am on a MacBook Pro, running the latest version of Mountain Lion. I really need some help, I have managed some how to damage my .bash_profile (I think) so that every time I open up the terminal I get the error listed below. -bash: export: `/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/go/bin': not a valid identifier -bash: export: `/Users/rob/Applications/sbt/bin:': not a valid identifier env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory -bash: tar: command not found -bash: grep: command not found -bash: cat: command not found -bash: find: command not found I am not sure what has happened, I have no sudo, cd or any normal commands. The only way I have been able to get to any of the main directories is through the go to folder command in finder and try to find the file to no avail. To top it all off I think I created a file that might be causing the issue, I wanted to edit the .bash_profile so I typed sudo nano ./bash_profile This open a new file in nano which I think was then saved. After this I opened the real .bash_profile to add in the path for node.js. If I can get to the .bash_profile I think I can get it back on track but I can't find it, should I reinstall bash? If so how would I do that on a mac, I tried using brew install bash to which I get -bash: brew: command not found I am really stuck if anyone can help I would be really appreciated. Many thanks

  • why is $0 set to -bash?

    - by James Shimer
    First login process name seems to be set to "-bash", but if I subshell then it becomes "bash". for example: root@nowere:~# echo $0 -bash root@nowere:~# bash root@nowere:~# echo $0 bash -bash is causing some scripts to fail, such as . /usr/share/debconf/confmodule exec /usr/share/debconf/frontend -bash Can't exec "-bash": No such file or directory at /usr/share/perl/5.14/IPC/Open3.pm line 186. open2: exec of -bash failed at /usr/share/perl5/Debconf/ConfModule.pm line 59 Anyone know the reason $0 is set to -bash?

  • Bash history handling with multiple terminals

    - by zetah
    I use mainly Terminator, and it's usually opened with 3 split terminal windows. I also use Gnome terminal for various reasons. I'm wondering how is bash history handled in this case as I sometimes miss previously issued commands when I run history For example, my prompt shows current bash history line (\!) and if I launch Terminator with 3 split terminal windows I get same history line (let's say 100) on all terminals. Which history will be saved? Also launching Gnome Terminal after using Terminator I get line 100 at startup regardless all commands issued before in Terminator

  • launching a program from bash causes bash to go to new prompt

    - by Dan Dman
    When I run a program from the console, e.g. me@box:~$ firefox I expect the console to log error messages (I think this is std out or std err?) and other items from the program, firefox in this case. But today I notice that bash just opens the program and goes to a new prompt, e.g. me@box:~$ firefox me@box:~$ How do I launch a program from bash such that error messages will be written to the console? Why is it that some programs operate this way by default and others (firefox) do not?

  • Bash alias and bash function with several arguments

    - by sanemat
    I want to use both bash alias and bash function with several arguments. I emulate svn sub commands. $ svngrep -nr 'Foo' . $ svn grep -nr 'Foo' . My expectation is both act as below: grep --exclude='*.svn-*' --exclude='entries' -nr 'Foo' . But actual, only alias ('svngrep') does well, function ('svn grep') causes invalid option error. How to write my .bashrc? #~/.bashrc alias svngrep="grep --exclude='*.svn-*' --exclude='entries'" svn() { if [[ $1 == grep ]] then local remains=$(echo $@ | sed -e 's/grep//') command "$svngrep $remains" else command svn "$@" fi }

  • How to debug a .bash_profile

    - by Blankman
    I was updating my .bash_profile, and unfortunetly I made a few updates and now I am getting: env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory env: bash: No such file or directory -bash: tar: command not found -bash: grep: command not found -bash: cat: command not found -bash: find: command not found -bash: dirname: command not found -bash: /preexec.sh.lib: No such file or directory -bash: preexec_install: command not found -bash: sed: command not found -bash: git: command not found My bash_profile actually pulls in other .sh files (sources them) so I am not exactly sure which modification may have caused this. Now if I even try and to a list of files, I get: >ls -bash: ls: command not found -bash: sed: command not found -bash: git: command not found Any tips on how to trace the source of the error, and how to be able to use the terminal for basic things like listing files etc?

  • How do I start bash in 13.04?

    - by Maik Klein
    I have a bash script that I need to execute. It seems that I can't run in in my terminal because it has a slightly different syntax. I could run the first file like bash ./configure but it produces a makefile that I can not use. If I try bash make it tells me that it can't execute make. How do I run this make file in bash? I tried cd /usr/bin ./bash but it tells me that it can't find bash. So how do I start bash?

  • Bash script to create mass series of directories

    - by Volomike
    I need to create a Bash script to go into every user's home folder, seek out a wp-content folder, create a directory uploads under it, and then chmod 0756 uploads. How do I achieve this? I imagine I need to use find with a regexp/regex, and then tell it to run another bash script on the results.

  • Unable to delete a file using bash script

    - by user3719091
    I'm having problems removing a file in a bash script. I saw the other post with the same problem but none of those solutions solved my problem. The bash script is an OP5 surveillance check and it calls an Expect process that saves a temporary file to the local drive which the bash script reads from. Once it has read the file and checked its status I would like to remove the temporary file. I'm pretty new to scripting so my script may not be as optimal as it can be. Either way it does the job except removing the file once it's done. I will post the entire code below: #!/bin/bash #GET FLAGS while getopts H:c:w: option do case "${option}" in H) HOSTADDRESS=${OPTARG};; c) CRITICAL=${OPTARG};; w) WARNING=${OPTARG};; esac done ./expect.vpn.check.sh $HOSTADDRESS #VARIABLES VPNCount=$(grep -o '[0-9]\+' $HOSTADDRESS.op5.vpn.results) # Check if the temporary results file exists if [ -f $HOSTADDRESS.op5.vpn.results ] then # If the file exist, Print "File Found" message echo Temporary results file exist. Analyze results. else # If the file does NOT exist, print "File NOT Found" message and send message to OP5 echo Temporary results file does NOT exist. Unable to analyze. # Exit with status Critical (exit code 2) exit 2 fi if [[ "$VPNCount" > $CRITICAL ]] then # If the amount of tunnels exceeds the critical threshold, echo out a warning message and current threshold and send warning to OP5 echo "The amount of VPN tunnels exceeds the critical threshold - ($VPNCount)" # Exit with status Critical (exit code 2) exit 2 elif [[ "$VPNCount" > $WARNING ]] then # If the amount of tunnels exceeds the warning threshold, echo out a warning message and current threshold and send warning to OP5 echo "The amount of VPN tunnels exceeds the warning threshold - ($VPNCount)" # Exit with status Warning (exit code 1) exit 1 else # The amount of tunnels do not exceed the warning threshold. # Print an OK message echo OK - $VPNCount # Exit with status OK exit 0 fi #Clean up temporary files. rm -f $HOSTADDRESS.op5.vpn.results I have tried the following solutions: Create a separate variable called TempFile that specifies the file. And specify that in the rm command. I tried creating another if statement similar to the one I use to verify that file exist and then rm the filename. I tried adding the complete name of the file (no variables, just plain text of the file) I can: Remove the file using the full name in both a separate script and directly in the CLI. Is there something in my script that locks the file that prevents me from removing it? I'm not sure what to try next. Thanks in advance!

  • bash doesn't keep history

    - by yohbs
    I run Ubuntu 12.04, and for some reason bash does not keep my command history. the ~/.bash_history file contains only 3 commands that I typed a few months ago. How can I fix this?

ORIGINAL QUESTION I have two executable files I downloaded and am trying to add to the path. They are located in /home/user/folder and the specific files are /home/user/folder/app1 /home/user/folder/app2 Both app1 and app2 have the executable flag set to all (user, group, other). I can execute the files if I am in /home/user/folder and I execute these commands ./app1 ./app2 However I can't run them from elsewhere. I added this line to my .profile PATH="$PATH:/home/user/folder" and then sourced the path with . /home/user/.profile and I can see app1 and app2 when I use command completion (pressing tab). However here is what happens when I try to run app1 or app2 with the following commands (the following only shows 'app1' but the same is true of 'app2') user@comp:~$ app1 -bash: app1: command not found user@comp:~$ /home/user/folder/app1 -bash: app1: command not found user@comp:~/folder$ ./app1 (program runs) I'm stumped :), I must have missed something simple. Thanks for your help!!

  • Ubuntu keyboard detection from bash script

    - by Ryan Brubaker
    Excuse my ignorance of linux OS/hardware issues...I'm just a programmer :) I have an application that calls out to some bash scripts to launch external applications, in this case Firefox. The application runs on a kiosk with touch screen capability. When launching Firefox, I also launch a virtual keyboard application that allows the user to have keyboard input. However, the kiosk also has both PS/2 and USB slots that would allow a user to plug-in a keyboard. If a keyboard were plugged in, it would be nice if I didn't have to launch the virtual keyboard and provide more screen space for the Firefox window. Is there a way for me to detect if a keyboard is plugged in from the bash script? Would it show up in /dev, and if so, would it show up at a consistent location? Would it make a difference if the user used a PS/2 or USB keyboard? Thanks!

There's no typical <directory> <username>$, no autocompletion (bash-completion is installed), and no use of arrow key, etc. I'm suspecting bash.bashrc is not sourced or something? How do I get the standard bash features working? edit: bash.bashrc and profile etc appears to exist in the filesystem

  • Finding the definition of a bash function

    - by pythonic metaphor
    I work in an environment that has a lot of legacy shell script magic lying around. One thing used heavy from the command line are bash functions that get sourced from some file included from some file included from some file ... included in my .bash_profile. Is there a way to get the definition or even better the location of the definition of these functions without tracking them down through 5 levels of includes?

  • Properly escaping forward slash in bash script for usage with sed

    - by user331839
    I'm trying to determine the size of the files that would be newly copied when syncing two folders by running rsync in dry mode and then summing up the sizes of the files listed in the output of rsync. Currently I'm stuck at prefixing the files by their parent folder. I found out how to prefix lines using sed and how to escape using sed, but I'm having troubles combining those two. This is how far I got: source="/my/source/folder/" target="/my/target/folder/" escaped=`echo "$source" | sed -e 's/[\/&]/\\//g'` du `rsync -ahnv $source $target | tail -n +2 | head -n -3 | sed "s/^/$escaped/"` | awk '{i+=$1} END {print i}' This is the output I get from bash -x myscript.sh + source=/my/source/folder/ + target=/my/target/folder ++ echo /my/source/folder/ ++ sed -e 's/[\/&]/\//g' + escaped=/my/source/folder/ + awk '{i+=$1} END {print i}' ++ rsync -ahnv /my/source/folder/ /my/target/folder/ ++ sed 's/^//my/source/folder//' ++ head -n -3 ++ tail -n +2 sed: -e expression #1, char 8: unknown option to `s' + du 80268 Any ideas on how to properly escape would be highly appreciated.

  • Handle filename with spaces inside Bash-script

    - by ifischer
    In my Bash-script i have to handle filenames with spaces. These are the important lines inside my script: mp3file="/media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\ Vol.5\ \[MP3PRO\]/01\ -\ Nofx\ -\ Pump\ up\ the\ Valium.mp3" echo "Command: mp3info -x `echo $mp3file`" mp3info -x `echo $mp3file` Unfortunately, the command does not work, because the filename is splitted: mp3info: invalid option -- '\' mp3info: invalid option -- '\' Error opening MP3: /media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\: No such file or directory Error opening MP3: Vol.5\: No such file or directory Error opening MP3: \[MP3PRO\]/01\: No such file or directory Error opening MP3: Nofx\: No such file or directory Error opening MP3: Pump\: No such file or directory Error opening MP3: up\: No such file or directory Error opening MP3: the\: No such file or directory Error opening MP3: Valium.mp3: No such file or directory I also tried to add a custom IFS as i read on some forums: SAVEIFS=$IFS IFS=$(echo -en "\n\b") # Script like above IFS=$SAVEIFS But this way, i'm getting the error Error opening MP3: /media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\ Vol.5\ \[MP3PRO\]/01\ -\ Nofx\ -\ Pump\ up\ the\ Valium.mp3: No such file or directory I tried quite a while now but i cannot get my script to work. What is strange is that if i'm running the same command that my script should create manually (echoing it inside my script) on the Shell, it actually works. But not inside my script. Any hints?

  • Run mplayer from bash in background without extra bash

    - by Emanuel Berg
    I would like to watch a movie with mplayer from bash in the background, like I do with all programs and there has never been any problems: mplayer Kick* & if you'd like to see Kickboxer, for example. But, this doesn't bring up the window, instead it says the process is stopped. I can bring the movie window up with fg mplayer, but then the CLI is unavailable. (This is -- as far as I can see anyway -- equivalent to mplayer Kick*). I'm able to work around the problem like this: $(mplayer Kick*) & But then I get two extra bashes (I see this with ps). It is not really a problem as those closes down when I Alt-F4 the movie, but it is still undesirable. I guess I'm most annoyed with having to type that extra stuff, so if you come up with an alias or function, that would be OK, to. Although, it wouldn't hurt me to learn what's going on. Edit: Hm, it doesn't even seem to work the way I said. The "work"around is not reliable. Forget about it.

  • skipping a variable using while read in bash

    i'm reading a few variables from a file using while read a b c; do (something) done < filename is there an elegant way to skip a variable (read in an empty value), i.e. if I want a=1 b= c=3, what should I write in the file? Right now i'm putting 1 "" 3 and then use b=$(echo $b | tr -d \" ) but this is pretty cumbersome, IMHO any ideas?

  • bash alias doesn't carry over with sudo

    - by agent154
    I'm curious if there's a way to get my .bash_profile to work when I sudo a program. For example, I have it set to alias emerge='emerge -av' so that I can install software, and it will always ask me if I want to proceed before downloading and installing. However I just noticed when I sudo emerge foo, it defaults to just the plain command emerge foo instead of emerge -av foo. Only thing that comes to mind to fix this is to also put the alias in root's .bash_profile, but I don't want to have to resort to that since I will always have to make changes in two places when I want to add stuff to my own profile. Is there another way around this that I'm unfamiliar with?

I may have used sudo. Is sudo history stored somewhere else? If so how do I access it? Much thanks for any insight.
