Error byte count and cut command
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
