Code:
 ls x 2>&1 | output_log

Basically what I am looking is to format command out put. I tried in below way also
ls -lrt 2>&1 | output_log
[INFO][Feb 08 16:11:10] total 112


I can see only first line in the output. Rest of the lines are missing.

Is it about this?
Code:
#!/usr/bin/env bash
# File: 	pipe
#
#	Variables
#
	C=0
#
#	Action & Display
#
	# Prepare arg list
	if [ $# -eq 0 ]
	then	[ -t 0 ] && printf "Input: "
		read input
	else	input=$@
	fi
	
	#Parse args
	for a in $input
	do
		echo "$C -- some text preparations $a"
		C=$(( $C + 1 ))
	done

Command / Output:
Code:
echo x y z | pipe
0 -- some text preparations x
1 -- some text preparations y
2 -- some text preparations z

As you see i've reused the template from ChubblerXL.

Hi Sea,

Thanks for your reply. What I am looking is to format the out put. I want to format even when we have an error. It is working fine when we have o/p but it is failing when we have an error or output contains more than single line.

You cannot 'format' an error message.
But you can form an error message, as in catching values that would cause an error, and then format a message and print it to the user.
However, that is another step.

Could you provide some sample input, desired output and what you have tried so far?
