Shell Programming and Scripting

Hi All,

Am in need of some inputs to overcome the following problem,

A tar file(/var/execute/scripts/ that contains different types of scripts(may be perl,shell, python etc...). I have written a shell script which is located @ /var/execute.sh to untar the file in some location say (/tmp/scripts/). and need to execute the scripts from the path /tmp/scripts/a.sh,b.pl,c.py. When i executing the execute.sh from /var, its giving error for perl and python scripts.(used pushd, popd to move into /tmp/scripts while executing the scripts in background with . dot operator).

Code:

chmod +x /tmp/scripts*
dos2unix /tmp/scripts/* > /dev/null 2>&1
pushd /tmp/scripts > /dev/null
for scriptfile in /tmp/scripts/* ;do
filecheck=`file $scriptfile | grep
. $scriptfile &
done
popd /tmp/scripts > /dev/null 2>&1

Any help is appreciated
Advance Thanks!!!!!!!!

I see the following:

1. The first line does change the permissions on /tmp/scripts and not on the content of /tmp/scripts. Shoudln't this line read chmod +x /tmp/scripts/* ?

2. I assume that the line starting with filecheck=`... is not complete because I do not see a closing `

3. You are running your scripts with . $scriptfile &. This means that the scripts will be run in the current shell, overriding the #! line at the top of your scripts.

With this . command, you basically tell your current shell to execute perl scripts and run perl commands. This will fail obviously.

You might be better of running your scripts like: ./$scriptfile &
