I need help with running multiple commands within one system call.

[rsm06]

Example:
I run a perl script from my c:\
the command I want to run is first change directory from C:\ to z:
then in Z: I want to run the dir command and performs some more commands (example findstr) and send output to a file.
Next I want to cd in R:\ and so same as last step.

How can I make this happen in perl?

Oops, I posted my comment in the wrong thread. [post removed]

Let me finish another post, then I'll come back and answer your question.

chdir

system

Instead of using the system function to execute findstr, I'd use open and grep.

open
grep

Why do you need a single system call?

One option you have is to build and execute a CMD script, if you're willing to go to that level of effort.

Also, what's wrong with using some form of fileglobing to build your list?

Tahnks to all who replied. I used the chdir and system command to do what I wanted. Here is the script I am now succesfuly running:

print ("\nEnter the target view ");
chomp($target = <STDIN>);
system("cleartool startview $target");
 
print ("\nEnter the source view\n");
chomp($source = <STDIN>);
system("cleartool startview $source");
 
print ("\nEnter VOB\n");
chomp($vob = <STDIN>);
system("cleartool mount \\$vob");
 
$cwd = ("v:\\$target\\$vob");
chdir ($cwd);
 
system("cleartool findmerge . -ftag $source -print >> c:\\versions.txt");
 
<more script> .....

How are you handling the case when the user enters an invalid value and cleartool fails?

[rsm06]

I am using the until loop to look for the 3 valid entries that require the input. Until the entires are found to be valid which is checked one at a time against an array the user cannot proceed.

Its just that I didn't see any error checking on the system calls. My thought was out of scope for your question, though.

Good luck getting it done.
