• Using bash shell from within PHP

  - by Dan

  Hi everyone, In my terminal window (using Max OS X) my shell is bash. However when I run a command in PHP via shell_exec or backtick operators I see that PHP is using the Bourne Shell (sh). Here's an example of what I'm seeing: From within my terminal window: $ echo $0 - bash Also if I call php as follows: $ php -r "echo shell_exec('echo $0');" -bash However, if I create a script called test.php with the following: <?php echo shell_exec('echo $0'); ?> And then run test php I get the following: $ php test.php sh I'm wanting to use the bash shell when calling shell_exec - why is it choosing the Bourne shell and can I force it to use bash? Thanks! Dan

• Bash on Snow Leopard doesn't obey terminal colours

  - by karbassi

  With the new version of Snow Leopard, OSX upgraded the bash version to GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0). Now, my .bashrc sets the following settings: # Colors export TERM=xterm-color export GREP_OPTIONS='--color=auto' GREP_COLOR='1;32' export CLICOLOR=1 export LSCOLORS=ExGxFxDxCxHxHxCbCeEbEb # Setup some colors to use later in interactive shell or scripts export COLOR_NC='\e[0m' # No Color export COLOR_WHITE='\e[1;37m' export COLOR_BLACK='\e[0;30m' export COLOR_BLUE='\e[0;34m' export COLOR_LIGHT_BLUE='\e[1;34m' export COLOR_GREEN='\e[0;32m' export COLOR_LIGHT_GREEN='\e[1;32m' export COLOR_CYAN='\e[0;36m' export COLOR_LIGHT_CYAN='\e[1;36m' export COLOR_RED='\e[0;31m' export COLOR_LIGHT_RED='\e[1;31m' export COLOR_PURPLE='\e[0;35m' export COLOR_LIGHT_PURPLE='\e[1;35m' export COLOR_BROWN='\e[0;33m' export COLOR_YELLOW='\e[1;33m' export COLOR_GRAY='\e[1;30m' export COLOR_LIGHT_GRAY='\e[0;37m' The colours are used later on for output. This used to work in previous version of OSX but not my output is as such: Some ideas that have not worked. Switching Terminal.app from 64-bit to 32-bit.

• Linux Bash Script, Single Command But Multiple Lines?

  - by Jay LaCroix

  I have the following script I wrote by searching Google, and it backs up my Linux system to an archive: #!/bin/bash # init DATE=$(date +20%y%m%d) tar -cvpzf /share/Recovery/Snapshots/$HOSTNAME_$DATE.tar.gz --exclude=/proc --exclude=/lost+found --exclude=/sys --exclude=/mnt --exclude=/media --exclude=/dev --exclude=/share/Archive / This works, but I am wondering if I can format the script to show the command over multiple lines, something like this, so it is easy to edit later: tar -cvpzf /share/Recovery/Snapshots/$HOSTNAME_$DATE.tar.gz --exclude=/proc --exclude=/lost+found --exclude=/sys --exclude=/mnt --exclude=/media --exclude=/dev --exclude=/share/Archive / That way it is easier to read and edit later. Is it possible to format a Bash script this way?

• Variable parsing with Bash and wget

  - by Bill Westrup

  I'm attempting to use wget in a simple bash script to grab a jpeg image from an Axis camera. This script outputs a file named JPEGOUT, instead of the desired output, which should be a timestamp jpeg (ex: 201209292040.jpg) . Changing the variable in the wget statement from JPEGOUT to $JPEGOUT makes wget fail with "wget: missing URL" error. The weird thing is wget parses the $IP vairable correctly. No luck on the output file name. I've tried single quotes, double quotes, parenthesis: all to no luck. Here's the script !/bin/bash IP=$1 JPEGOUT= date +%Y%m%d%H%M.jpg wget -O JPEGOUT http://$IP/axis-cgi/jpg/image.cgi?resolution=640x480&compression=25 Any ideas on how to get the output file name to parse correctly?

• Why does bash invocation differ on AIX when using telnet vs ssh

  - by Philbert

  I am using an AIX 5.3 server with a .bashrc file set up to echo "Executing bashrc." When I log in to the server using ssh and run: bash -c ls I get: Executing bashrc . .. etc.... However, when I log in with telnet as the same user and run the same command I get: . .. etc.... Clearly in the telnet case, the .bashrc was not invoked. As near as I can tell this is the correct behaviour given that the shell is non-interactive in both cases (it is invoked with -c). However, the ssh case seems to be invoking the shell as interactive. It does not appear to be invoking the .profile, so it is not creating a login shell. I cannot see anything obviously different between the environments in the two cases. What could be causing the difference in bash behaviour?

• Bash Script Exits su or ssh Session Rather than Script

  - by Russ

  I am using CentOS 5.4. I created a bash script that does some checking before running any commands. If the check fails, it will simply exit 0. The problem I am having is that on our server, the script will exit the su or ssh session when the exit 0 is called. #!/bin/bash # check if directory has contents and exit if none if [ -z "`ls /ebs_raid/import/*.txt 2>/dev/null`" ]; then echo "ok" exit 0 fi here is the output: [root@ip-10-251-86-31 ebs_raid]# . test.sh ok [russ@ip-10-251-86-31 ebs_raid]$ as you can see, I was removed from my sudo session, if I wasn't in the sudo session, it would have logged me out of my ssh session. I am not sure what I am doing wrong here or where to start.

• Running SQL*Plus with bash causes wrong encoding

  - by Petr Mensik

  I have a problem with running SQL*Plus in the bash. Here is my code #!/bin/bash #curl http://192.168.168.165:8080/api_test/xsql/f_exp_order_1016.xsql > script.sql wget -O script.sql 192.168.168.165:8080/api_test/xsql/f_exp_order_1016.xsql set NLS_LANG=_.UTF8 sqlplus /nolog << ENDL connect login/password set sqlblanklines on start script.sql exit <<endl I download the insert statements from our intranet, put it into sql file and run it through SQL*Plus. This is working fine. My problem is that when I save the file script.sql my encoding goes wrong. All special characters(like íášc) are broken and that's causing inserting wrong characters into my DB. Encoding of that file is UTF-8, also UTF-8 is set on the XSQL page on our intranet. So I really don't know where could be a problem. And also any advices regarding to my script are welcomed, I am total newbie in Linux scripting:-)

• Bash Script to Back Up Backs Up Itself

  - by Jay LaCroix

  I have the following bash script that creates a tar.gz of my filesystem on a Kubuntu PC. The problem is, that it also tries to backup the tar.gz backup file, even though I am storing the backup in /tmp and omitting /tmp from the backup. I am wondering why it's backing up the file in /tmp even though I told it not to. #!/bin/bash # init DATE=$(date +20%y%m%d) sudo tar -cvpzf /tmp/`hostname`_$DATE.tar.gz \ --exclude=/proc \ --exclude=/lost+found \ --exclude=/sys \ --exclude=/mnt \ --exclude=/media \ --exclude=/dev \ --exclude=/tmp \ --exclude=/home/jlacroix/Desktop \ --exclude=/home/jlacroix/Documents \ --exclude=/home/jlacroix/Music \ --exclude=/home/jlacroix/Pictures \ --exclude=/home/jlacroix/Projects \ --exclude=/home/jlacroix/Roms \ --exclude=/home/jlacroix/Videos \ --exclude=/home/jlacroix/.VirtualBox\ VMs \ --exclude=/home/jlacroix/.SpiderOak \ / scp /tmp/`hostname`_$DATE.tar.gz jlacroix@Pluto:/share/Recovery/Snapshots sudo rm /tmp/`hostname`_$DATE.tar.gz

• Bash preexecute

  - by Alex_Bender

  I'm trying to write bash command wrapper, which will be patch bash current command on the fly. But i'm faced with the problem. As i'm not a good Shell user, i can't write right expression of variable assignment in string. See bellow: I'm set trap to preexecute, through this: alex@bender:~$ trap "caller >/dev/null || xxx \"\${BASH_COMMAND}"\" DEBUG; I want change variable BASH_COMMAND, do something like BASH_COMMAND=xxx ${BASH_COMMAND} but i don't know, how i need escaping variables in this string NOTE: xxx -- my custom function, which must return some value, if in end of command situated word teststr function xxx(){ # find by grep, if teststr in the end `echo "$1" | grep "teststr$" >/dev/null`; # if true ==> do if [ "$?" == "0" ]; then # cut last 6 chars (len('teststr')==6) var=`echo "$1" | sed 's/......$//'`; echo "$var"; fi } How can i do this stuff?: alex@bender:~$ trap "caller >/dev/null || ${BASH_COMMAND}=`xxx $BASH_COMMAND`" DEBUG;

• Bash: Variable substitution in variable name with default value

  - by krissi

  i have the following variables: # config file MYVAR_DEFAULT=123 MYVAR_FOO=456 #MYVAR_BAR unset # program USER_INPUT=FOO TARGET_VAR=<need to be set> If the USER_INPUT is "foo", I want TARGET_VAR to be the value of MYVAR_FOO (TARGET_VAR=456). If USER_INPUT is "bar" I want TARGET_VAR to be set to MYVAR_DEFAULT (123), because MYVAR_BAR is unset. I prefer it to be sh-compatible and as a substitution string. But it might also be bash compatible and/or in a function. I got these snippets: # Default values for variable (sh-compatible) echo ${MYVAR_FOO-$MYVAR_DEFAULT} # Uppercase (bash compatible) echo ${USER_INPUT^^} I would need something like this: TARGET_VAR="${MYVAR_${USER_INPUT^^}-$MYVAR_DEFAULT}" # or somecommand -foo "${MYVAR_${USER_INPUT^^}-$MYVAR_DEFAULT}" This is to switch a bunch of variables between multiple "profiles". In the example, FOO and BAR are profiles. New profiles should be added easily, in this example there would be an implicit profile named BAZ, too, all variables to their default values. Unfortunately it is not that easy. Do you have an idea to solve this? Thanks in advance, krissi

• How to programmatically query bash completion for given string

  - by Ryan McKay

  I want to ask bash how it would complete a string as if I had typed it in a shell and hit tab. For example, if I type ls /[TAB][TAB] I see the list of files and dirs in / that could possibly complete the ls command. How do I ask bash how it would complete 'ls /' without typing it and hitting tab? I want something like: query_complete 'partial command line string' I read the man page for complete and compgen, but couldn't figure out how to do it with them. Note: 'ls /' is not the actual command I'm interested in, just an example. I am looking for a general solution for any arbitrary string representing a partial command line.

• Going to directory using bash variables doesn't work when directory names have spaces

  - by gsingh2011

  Let's say I want to store the following command in a variable cd "/cygdrive/c/Program Files/" So I do this dir="cd \"/cygdrive/c/Program Files/\"" That should store the command to navigate to the Program Files directory, so when I type $dir it takes me to that directory. To check that the quotations have been properly escaped, I type echo $dir which gives me cd "/cygdrive/c/Program Files/" So everything should be working fine. However, when I type, $dir I get bash: cd: "/cygdrive/c/Program: No such file or directory What am I doing wrong? I'm using Cygwin, but I assume this problem applies to bash in general.

• Bash window title not restored after exit

  - by forthrin

  I have a problem with the window title in the Terminal window on OS X: Start Terminal. Window title is "bash" Type "ssh external" to connect to an external server. Window title is "user@external:~" Type "exit". I am now back at my local machine, but the window title still says "user@external:~". How do I make the window title return to "bash", which I assume would be correct since I have logged out of the external server and returned to my local machine? My ~/.bash_profile has the same PS1 value: export PS1='\w$ '

• Bash: create anonymous fifo

  - by Adrian Panasiuk

  We all know mkfifo and pipelines. The first one creates a named pipe, thus one has to select a name, most likely with mktemp and later remember to unlink. The other creates an anonymous pipe, no hassle with names and removal, but the ends of the pipe get tied to the commands in the pipeline, it isn't really convenient to somehow get a grip of the file descriptors and use them in the rest of the script. In a compiled program, I would just do ret=pipe(filedes); in Bash there is exec 5<>file so one would expect something like "exec 5<> -" or "pipe <5 >6" -is there something like that in Bash?

• how to check in a bash script where the shell is run from

  - by nass

  I am fuzzy about how to set a command in a script to be run only when the shell is running within an X session. basically, in ~/.bashrc I set my keyboard maps as setxkbmap -layout 'us,gr' -variant 'altgr-intl,extended' -option grp:alt_shift_toggle If I am connecting through putty , or otherwise, and i just open a command prompt window, I DONT want this command to run. If on the other hand, i have an X session running (locally or remotely) I want this command to run. how can I do this checking in a bash script? Is there a bash environment variable I can be looking at? some other way? Thank you for your help

• Running a bash script from an HTML link or button

  - by Andrew

  I have a webserver that's hosting lots of images. I want the client to be able to press a button or a link, which will run a bash script, which will create a video based on all these pictures. The script I'm trying to run is this: #!/bin/bash # cd to the directory cd /var/www/gallery # use ffmpeg to make video ffmpeg -pattern_type glob -i 'img-*jpg' -r 1 video.mp4 # Take the first file in the directory and name it video.mp4.jpg (for thumbnail) cp `ls | sort -n | head -1` video.mp4.jpg The script is located on the server. So when the client clicks the link or button, the script will run, and the video is created. I've tried both solutions listed here but I can't seem to get it to work. I have php installed on my server.

• Bash: Created a ~ (Tilde) in a directory by accident

  - by user1500360

  I'm a beginner to using bash on OSX, and I somehow created a ~ dir in a project subfolder. (It appears as a directory, rather than a symlink.) Is there a safe way to get rid of this ~ directory instance without bash expanding the tilde wiping my local user directory? This is a really goofy question, but it would be a huge help to figure out how to deal with this. Solution: I ended up using rm -rfi ./\~, which worked safely. Thanks, everyone!
