remove file extension
Hi ALL,
I'm new to this forum.
Thanks and congrats to all for their great efforts building this site simply superb for all unix administrators.
My requirement is to remove extensions of the files in the current directory. I'm doing it using below script which is working but i think it is very inefficient as i use lot of variables.I want to get done by avoiding usage of tempfile file and any other temp files being used.
#!/usr/bin/bash
ls -l |awk '{print $9}' >/list
cat /list |while read line
do
echo $line >/tempfile
first=`cut -f1 -d'.' /tempfile`
echo $first >>/output.txt
mv $line $first
done
Thanks
Praveen RK

test::tempdir
Test::TempDir(3pm) User Contributed Perl Documentation Test::TempDir(3pm)
NAME
Test::TempDir - Temporary files support for testing.
SYNOPSIS
use Test::TempDir;
my $test_tempdir = temp_root();
my ( $fh, $file ) = tempfile();
my $directory_scratch_obj = scratch();
DESCRIPTION
Test::TempDir provides temporary directory creation with testing in mind.
The differences between using this and using File::Temp are:
o If "t/tmp" is available (writable, creatable, etc) it's preferred over $ENV{TMPDIR} etc. Otherwise a temporary directory will be used.
This is "temp_root"
o Lockfiles are used on "t/tmp", to prevent race conditions when running under a parallel test harness.
o The "temp_root" is cleaned at the end of a test run, but not if tests failed.
o "temp_root" is emptied at the begining of a test run unconditionally.
o The default policy is not to clean the individual "tempfiles" and "tempdirs" within "temp_root", in order to aid in debugging of failed
tests.
EXPORTS
temp_root
The root of the temporary stuff.
tempfile
tempdir
Wrappers for the File::Temp functions of the same name.
The default options are changed to use "temp_root" for "DIR" and disable "CLEANUP", but these are overridable.
scrach
Loads Directory::Scratch and instantiates a new one, with the same default options as "tempfile" and "tempdir".
SEE ALSO
File::Temp, Directory::Scratch, Path::Class
