Hi all...

I have a script that is in Unix. I wanted to know is there any difference between output of ls command in unix and linux

In Unix

Code:

ls -ltr | awk '{print $9}'

In linux output is something similar to

Code:

drwxrwxrwx 2 vinay vinay 4096 2010-02-04 20:31 test

According to above output nothing will be displayed for

Code:

ls -ltr | awk '{print $9}'

ls -ltr | awk '{print $8}' will give test as ouptut in Linux.

I wanted to check the output format for ls -ltr, Anyone using Unix systems may paste a sample output of the command ls -ltr..

Thanks...

The default date format in ls can vary across systems; never try to parse the output from ls.
Simple ls (no options) with filenames that have no spaces is just about safe ... maybe.

Parsing output from the stat command (for each file) may be more portable.
