byte count and cut command

hemangjani · #1 (**permalink**) 04-10-2007

1. Is there a way to count the number of bytes of a variable?
example:
abc@yahoo.com is 13 bytes

2. Cut command only allows one byte for delimiter
example: cut -f1 -d'.'
delimited by period. Is there a way to have two or more characters in the delimiter field?

thanks in adavance.

1.

Code:

var=abc@yahoo.com
echo ${#var}

2.

Use awk.

ksh/bash
1.

Code:

$ a=abc@yahoo.com 
$ echo ${#a}
13

Code:

$ echo "abc.|de" | awk -F'.|' '{ print $1}'
abc

(note not all awks will allow this, on solaris use nawk)

1)

Code:

# printf "abc@yahoo.com" |wc -c
13

2) another way,

Code:

# var=abc@#yahoo.com
# IFS="@#"
# echo $var
abc  yahoo.com
# set - $var
# echo $1
abc
# echo $3
yahoo.com
