This would be part of a reverse-engineering project. To determine and document what a shell script (ksh, bash, sh) does, it is comfortable, if you have information about what other programs/scripts it calls. How could one automate this task? Do you know any program or framework that can parse a shell script? This way for instance, I co...
I have an sh script that contains the line $PHP_COMMAND -r 'echo get_include_path();' I can not edit this script, but I need the eventual command line to be (equivalent to) php -d include_path='/path/with spaces/dir' -r 'echo get_include_path();' How can I achieve this? Below is a script that demonstrates the problem. #!/bin/sh...
Our application has a couple of shell scripts that are called from web-based Oracle Forms 10g, running on multiple Solaris 10 servers.

cat hosts.txt | while read h; do telnet $h; done When I run this, it telnets to first host which denies the connection but then exists instead of looping over the other hosts in the file. Why is it exiting the loop after the first host and how can I fix it? Thanks. ...
So, the idea is to have a script that tries to run a command, and if the command fails it shows up any warnings/errors. My try: $ cat try.sh #! /bin/sh tempfile=`tempfile 2>/dev/null` || tempfile=/tmp/temp$$ trap 'rm -f $tempfile >/dev/null 2>&1' 0 trap 'exit 2' 1 2 3 15 echo "$@" if !

I have a script which executes a git-pull when I log in. The problem is, if I su to a different user and preserve my environment with an su -lp, the script gets run again and usually gets messed up for various reasons because I'm the wrong user. Is there a way to determine in a shell script whether or not I'm currently SUing? I'm looking...
I have a basic web server that I generated from the mochiweb framework. To start it I use the start.sh script that the framework automatically generates. Everything works fine and the server starts up. Now I have one more mochiweb server that I want to start along with the first one. Again, this starts up perfectly standalone with its st...
I'm working on a project where we are dealing with importing/exporting data from database tables using ksh scripts and Perl scripts. We have an existing process to export data from a table to a file and it is then imported into another system. Here's the catch - the export process dumps out pipe delimited files while the system that is...

This would be the output that I need: 1,cake:01351 12...

Right now this outputs the value I need on stdout. How can I capture it into a variable so I can use it in the rest of the script? Requirements: The script needs to be all in one file. I'd prefer not to write any temp files, if possible. . #!/bin/bash cat << EOF | xsltproc - ../pom.xml | tail -1 <?xml version="1.0"?> <xsl:stylesh...
