Grep Command Help

[jagadam]

Hi,

I need help in grabbing the value after comma from a comma separated file in linux.

Values in a file :

ABC,0
DEF,1
GHI,2
FJK,3

I need to grep value 0 if i pass ABC as a parameter to command.

i tried with grep 'ABC' filename | awk '{print $1}' but unsuccessful.

Could any one please help me.

Thanks in Advance.

You're also not testing if the file returned nothing for the GREP command, but you're still parsing the stdout of grep.

You were 'unsuccessful' how? A full explanation of what you tried and what happened when you tried it can go a long way towards getting a resolution out sooner rather than later.

yes it should be unsuccessful since there's no FS specified.
try:

Code: Select all

grep "ABC" filename|nawk -F, '{print $2}'

Code: Select all

pandeeswaran@ubuntu:~$ echo abc,0|grep abc|nawk -F, '{print $2}'
