Hi

The previous time you posted about the similar script I had a hard time understanding your request, so please include all the necessary details in your request. For example what are you going to do with the created files, move them, rename them,...? More details help us to help you.

The below script tested on a Linux machine.


Code:
for i in `ls | xargs file | awk -F: '! /gzip/{print $1}'`
 do
    gzip $i
 done

#Now the files have the extension gz. If you need to move the files in a different directory afterwards:

for i in `ls | grep gz`
 do
   mv $i /home/other_dir/
 done




Glad to hear you got the script working the first time.

znew

ZNEW(1) 						      General Commands Manual							   ZNEW(1)

NAME

       znew -	recompress .Z files to .gz files

SYNOPSIS

       znew [ -ftv9PK] [ name.Z ...  ]

DESCRIPTION

       Znew  recompresses  files  from .Z (compress) format to .gz (gzip) format.  If you want to recompress a file already in gzip format, rename
       the file to force a .Z extension then apply znew.

OPTIONS

       -f     Force recompression from .Z to .gz format even if a .gz file already exists.

       -t     Tests the new files before deleting originals.

       -v     Verbose. Display the name and percentage reduction for each file compressed.

       -9     Use the slowest compression method (optimal compression).

       -P     Use pipes for the conversion to reduce disk space usage.

       -K     Keep a .Z file when it is smaller than the .gz file; implies -t.

SEE ALSO

       gzip(1), zmore(1), zdiff(1), zgrep(1), zforce(1), gzexe(1), compress(1)

BUGS

       Znew does not maintain the time stamp with the -P option if cpmod(1) is not available and touch(1) does not support the -r option.
