Read file and run a command
Hi

I have jobs (some 1000) defined in a file and I want to read those jobs and run a a command.

For example:
jobs.txt

Code:
abc
efg

I want to read the entire file and run the following command
Code:
Delete -JOB "abc"
Deleteing abc...
Delete -JOB "efg"
Delete efg...

Can somebody help me with the shell script to do the following.

Many Thanks in advance
Karan

Please use code tags as required by forum rules!

Modifying jobs.txt is quite easy,
Code:
sed 's/^/Delete -JOB "/; s/$/"/'  jobs.txt
Delete -JOB "abc"
Delete -JOB "efg"

(assuming "Deleteing abc..." and "Delete efg..." are - inconsistent - log output) but I doubt you can "run" this unless you name an application to which you can supply it.

Hi RudiC,

Thanks for the reply.

yes I would want it in a for loop, as Would need to delete all the 1000 jobs from the database and Delete <jobname> is the command I would need to run.

Hope I am able to explain my requirement properly.

I don't understand your request. You could use above proposal to create the desired text and script a while loop to read (and work on/with) it, but as "Delete" is no *nix command afaik, you need to run an application to interpret it.

Code:
#!/bin/sh

while read a
do
    echo "Deleting $a..."
    echo "Delete -JOB \"$a\""
    Delete -JOB "$a"
done <jobs.txt

Note: I am assuming "Delete" is something you have already, as it's not a standard Unix command.
