Question: What is use of "cut" command ???
give some examples.
can we use "awk" or "sed" instead of "cut" ???
if yes then give some examples

Answer: This utility is use to cut out columns from a table or fields from each line of a file.

cut can be used as a filter.



Either the -b, -c, or -f option must be specified.



-b list

The list following -b specifies byte positions (for instance, -b1-72 would pass the first 72 bytes of each line). When -b and -n are used together, list is adjusted so that no multi-byte character is split.



-c list

The list following -c specifies character positions (for instance, -c1-72 would pass the first 72 characters of each line).



-d delim

The character following -d is the field delimiter (-f option only). Default is tab. Space or other characters with special meaning to the shell must be quoted. delim can be a multi-byte character.
