Customised Output
I want some customised output of following command:
$ls -a|sort
gives output as filenames line by line. But I want the output as filenames aeperated by tab? How can I get this?

Thanks in advance.

try:
Code:
ls -a|sort | xargs

Or.

Code:
ls -d $(ls -a | sort)

(although I think the basic ls output gives the files sorted anyway, so ls -a is the same as ls -a | sort)

Or all separated with tab (no newlines)

Code:
ls -a | sort | awk -v ORS="\t" '1'

Thanks for your reply. But I want to display the filenames seperated by tab. Actually, I am new to LInux. I dont know what is xargs?
Its better if you tell me for what we use xargs also.


Thanking you,

Ok...If you want it tab seperated, use the one below.

Code:
ls -a|sort | tr "\n" "\t"

What does '1' specify in this command?

ls -a | sort | awk -v ORS="\t" '1'

It is treated as a non-zero/not-null/TRUE expression pattern.
