Hi all,
Cut is a simpler alternative to sed command. Cut is very efficient and flexible..

The examples specified below is from Solaris 11.1 and  Redhat Enterprise Linux 6.4, however most of the Linux / Unix distributions supports the cut command.

We shall use the below file for our examples.

root@sol1:~/jk# cat testfile.txt
This is a test file to demonstrate "cut" command.
Cut can be used for line filtering.
Cut is simpler than awk and sed commands.
root@sol1:~/jk#


1. Select a field from a file.
You can combine -f and -d to print required field. -f specifies the field and -d specified the delimiter to be used to find the filed.

root@sol1:~/jk# cut -d':' -f1 /etc/passwd | head -5
root
daemon
bin
sys
adm
root@sol1:~/jk#
