Like i need to pass simple ls -ltrh >temp1 on a application server in mount point eg - /onestmp
how do i pass and capture the command.
How you pass the command depends on your programming language - if t's a shell script, you "pass" it exactly as you wrote it. With Perl, you'd use "system".
As you sent the output to a file, you just need to read that file to get the output. That's often the easiest way to do it, especially for something as simple as "ls" that you don't need to interact with. Programming feeding and reading one program from another is more complicated.

devel::trace
Trace(3pm) User Contributed Perl Documentation Trace(3pm)NAME
Devel::Trace - Print out each line before it is executed (like "sh -x")
SYNOPSIS
perl -d:Trace program
DESCRIPTION
If you run your program with "perl -d:Trace program", this module will print a message to standard error just before each line is executed.
For example, if your program looks like this:
#!/usr/bin/perl
print "Statement 1 at line 4
";
print "Statement 2 at line 5
";
print "Call to sub x returns ", &x(), " at line 6.
";
exit 0;
sub x {
print "In sub x at line 12.
";
return 13;
}
Then the "Trace" output will look like this:
>> ./test:4: print "Statement 1 at line 4
";
>> ./test:5: print "Statement 2 at line 5
";
>> ./test:6: print "Call to sub x returns ", &x(), " at line 6.
";
>> ./test:12: print "In sub x at line 12.
";
>> ./test:13: return 13;
>> ./test:8: exit 0;
This is something like the shell's "-x" option.
DETAILS
Inside your program, you can enable and disable tracing by doing
$Devel::Trace::TRACE = 1; # Enable
$Devel::Trace::TRACE = 0; # Disable
or
Devel::Trace::trace('on'); # Enable
Devel::Trace::trace('off'); # Disable
"Devel::Trace" exports the "trace" function if you ask it to:
import Devel::Trace 'trace';
Then if you want you just say
trace 'on'; # Enable
trace 'off'; # Disable
TODO
o You should be able to send the trace output to the filehandle of your choice.
o You should be able to specify the format of the output.
o You should be able to get the output into a string.
We'll see.
