  • Shell script syntax error: unexpected end of line

    - by user1557674
    I wrote a simple shell script to check for the existence of a xml file and if it exists, then rename an old xml file to be backup and then move the new xml file to where the old xml file was stored. #!/bin/sh oldFile="/Documents/sampleFolder/sampleFile.xml" newFile="/Documents/sampleFile.xml" backupFileName="/Documents/sampleFolder/sampleFile2.backup" oldFileLocation="/Documents/sampleFolder" if [ -f "$newFile" ] ; then echo "File found" #Rename old file mv $oldFile $backupFileName #move new file to old file's location mv $newFile $oldFileLocation else echo "File not found, do nothing" fi However, every time I try to run the script, I get 4 command not found messages and a syntax error: unexpected end of file. Any suggestions on why I get these command not found errors or the unexpected end of file? I double checked that I closed all my double quotes, I have code highlight :) EDIT: output from running script: : command not found: : command not found: : command not found1: : command not found6: replaceXML.sh: line 26: syntax error: unexpected end of file

  • Detecting when a process has finished (but not exited)

    - by Egwor
    I have a program that's run in unix (that I have no control over) that when finished prints 'Completed successfully' but does not exit. I want to automatically detect when the process finishes (by checking the output of the command), so that I can kill the process and so that I can proceed do other activities. The complexity comes because I want to be able to run multiples of these scripts concurrently. (One activity I need to do requires the script to be called with various inputs, but each time the script runs it takes a while to return, and so I want to do them in parallel) Has anyone done something similar to this? I could redirect the stderr and stdout output of the command to a temporary file which has a random file name, then tail the file and pipe to grep for the end conditions (I.e. the certain log lines). The problem is, surely tail -f would keep running, and so it would never exit. Should I poll? If so, what's the best approach?

  • Find -type d with no subfolders

    - by titatom
    Good morning ! This is a simple one I believe, but I am still a noob :) I am trying to find all folders with a certain name. I am able to do this with the command find /path/to/look/in/ -type d | grep .texturedata The output gives me lots of folders like this : /path/to/look/in/.texturedata/v037/animBMP But I would like it to stop at .texturedata : /path/to/look/in/.texturedata/ I have hundreds of these paths and would like to lock them down by piping the output of grep into chmod 000 I was given a command with the argument -dpe once, but I have no idea what it does and the Internet has not be able to help me determine it's usage Thanks you very much for your help !

    #include <iostream> using namespace std; int main() { short int enterVal; cout << "enter a number to say: " << endl; cin >> enterVal; system("say "%d"") << enterVal; return 0; } Is what I am currently trying. I want the user to enter a number and the system() function says it basically. The code above has an error which says " 'd' was not declared in this scope ". Thanks in advance.

  • Improved technique to store a filename in a variable?

    - by SDGuero
    Greetings, I need to store the filename of a log into a variable so my script can perform some checks on the daily log files. These logs always have a different name because they have a timestamp in the name. Currently I'm using a hodge podged method that pipes an ls command to sed, sort, cut, and tail in order to get the name out. CRON_LOG=$(ls -1 $LOGS_DIR/fetch_cron_{true,false}_$CRON_DATE*.log 2> /dev/null | sed 's/^[^0-9][^0-9]*\([0-9][0-9]*\).*/\1 &/' | sort -n | cut -d ' ' -f2- | tail -1 ) UPDATE: $CRON_DATE is supplied as an argument to the script. It is the date (to the day) that the log was created on. Sometimes multiple logs will exist for the same day so I want this to get the most recent one. A typical filename is fetch_cron_false_031810090452.log I'm pretty sure I kluged this together from some stuff I found google a few months ago. it works now but I'm not really happy with the technique. I have some ideas about how to do this better but I have had great success on this site before and thought it might be best to refer to the stackoverflow gods first. All answers are greatly appreciated. Thanks, Ryan

  • Changing find to echo

    - by waszak
    This is almost good find *.txt -print0 | xargs -0 rm -f And i want to have something like that echo *.txt ./zad3.sh | xargs -l rm -f First version is good because I can delete file with white spaces but I can't use my script to select file to delete. Second version I can select files but I can't delete file with white spaces. I want to find files with end on .txt and delete some of them. zad3.sh is a script wich is returning file name if i agree to delete it rm catch the name and delete it. It works only for file without white space and special characters. Second version is better but i cant put my script inside it. find *.txt -print0| xargs -0 ./zad3.sh |xargs rm -f it works almost but i cant pass arg to rm and part of my code Thx

  • Find and replace date within a file

    - by user1629011
    My apologies if my title is not descriptive enough, I believe the following will be. I have 3 files which are just plain text, within each file, is a date Date: 2012-08-31 for example I would like to get a command/script to find this and update to the current date, but the date will be ever changing and may not be known going in (without viewing the contents of the file Knowing what the date is, its simple enough with sed, but how can I do this knowing the syntax of the line I want to modify, but not the specific values. ("Date: " at least is unchanging)

  • How to pass in password to pg_dump?

    - by Mark
    I'm trying to create a cronjob to back up my database every night before something catastrophic happens. It looks like this command should meet my needs: pg_dump dbname | gzip > $(date +%Y-%m-%d).psql.gz Except after running that, it expects me to type in a password. I can't do that if I run it from cron. How can I pass one in automatically?

  • How do I manage a Python based daemon on Linux?

    - by BCS
    I have a working Python based program that I want to run as a daemon. Currently I'm doing it in a very hackish manner of starting it in with screen-d -m name session and killing it with pkill -f name. Eventually I'm doing to have to move this to the better system we use here (thus I don't want to modify the program) but in the interim, I'm looking for a cleaner way to do this. My current thinking is kick it off as a background task from an inti.d script but how do I bring it back down?

  • php/ssh2 script does not display the stdout to $stream

    - by kamal
    The following php script works for simple linux commands, like ps -ef , but when i use ./dstat -t -a , it seems to hang and i dont get the prompt back on my local machine. Kep in mind that all commands are executed over ssh on a remote host: <?php $target = time() . '_' . 'txt'; if($ssh = ssh2_connect('10.1.0.174', 22)) { if(ssh2_auth_password($ssh, 'root', 'kmoon77')) { //$stream = ssh2_exec($ssh, 'whoami'); $sCommand = 'dstat -a'; //$sCommand = 'ps -ef'; $stream = ssh2_exec($ssh, $sCommand); //$stream = ssh2_exec($ssh, 'pwd'); stream_set_blocking($stream, true); $data = ''; while($buffer = fread($stream, 4096)) { $data .= $buffer; } //fclose($stream); echo $data; // user } } ?>

  • How to programatically set a permanent environment variable in Linux?

    - by Richard
    I am writing a little install script for some software. All it does is unpack a target tar, and then i want to permanently set some environment variables - principally the location of the unpacked libs and updating $PATH. Do I need to programmatically edit the .bashrc file, adding the appropriate entries to the end for example, or is there another way? What's standard practice? Edit: The package includes a number of run scripts (20+) that all use these named environment variables, so I need to set them somehow (the variable names have been chosen such that a collision is extremely unlikely)

  • Using sed with html data

    - by StackedCrooked
    I'm having some problems using sed in combination with html. The following sample illustrates the problem: HTML="<html><body>ENTRY</body><html>" TABLE="<table></table>" echo $HTML | sed -e s/ENTRY/$TABLE/ This outputs: sed: -e expression #1, char 18: unknown option to `s' If I leave out the / from $TABLE so that it becomes <table><table> it works ok. Any ideas on how to fix it?

  • Removing a text block from a file : sed ?

    - by user555338
    Hi, Following an attack, I need to remove 4 lines of text added to .htaccess files in my site, and was thinking SED would be the way to go, but cannot see how in spire of many attempts. The added lines are RewriteEngine On RewriteCond %{HTTP_REFERER} ^http:// RewriteCond %{HTTP_REFERER} !%{HTTP_HOST} RewriteRule . http://targeturlhere.net/%{REMOTE_ADDR} I managed to create the script to remove added htaccess files containing those lines only, but for existing htaccess files in which that was appended I have to edit the file and cannot delete it. I cannot just remove line by line nor use "RewriteEngine On" as the start marker, as this instruction "RewriteEngine On" is sometimes legitimate elsewhere in the file. In most cases those lines are the last, but I guess in other files they could be in the middle, so I was trying to remove exactly that block - and have a script I could reuse in a similar case. (Edit: my 4 lines are below one another, no blank line in between but the editor here seems to either show no breakline, or one adding a blank line) Any hint or tip ? Thanks.

  • Concatenation awk outputs

    - by Rookie_22
    I'm using regex to parse NMAP output. I want the ip addresses which are up with the corresponding ports open. Now I've a very naive method of doing that: awk '/^Scanning .....................ports]/ {print substr ($2,1,15);}' results.txt awk '/^[0-9][0-9]/ {print substr($1,1,4);}' results.txt | awk -f awkcode.awk where awkcode.awk contains the code to extract numbers out of the substring. The first line prints all the ips that are up and 2nd gives me the ports. My problem is that I want them mapped to each other. Is there any way to do that? Even sed script would do.

  • Limit output of all Linux commands

    - by daniel
    I'm looking for a way to limit the amount of output produced by all command line programs in Linux, and preferably tell me when it is limited. I'm working over a server which has a lag on the display. Occasionally I will accidentally run a command which outputs a large amount of text to the terminal, such as cat on a large file or ls on a directory with many files. I then have to wait a while for all the output to be printed to the terminal. So is there a way to automatically pipe all output into a command like head or wc to prevent too much output having to be printed to terminal?

  • Run three shell script simultaneously

    - by user1419563
    I have three shell script which I am running as below- sh -x script1.sh sh -x script2.sh sh -x script3.sh So each script is executed sequentially one at a time after previous one finished executing. Problem Statement:- Is there any way I can execute all the three above scripts at same time from a single window? I just want to execute script1, script2, script3 at the same time. If you think of some cron JOB scheduling script1 at 3 AM, script2 at 3AM, script3 at 3AM (all three scripts at the same time, simultaneously). That's what I need, I need to execute all the three scripts simultaneously.
