I want to find out the record length of a fixed length file? I forgot the command. Any body know?

Code:

awk '{print length;exit}' filename

in shell (bash, zsh, ksh93):

Code:

<filename IFS= read;echo ${#REPLY}

Code:

> echo `echo "<EmailAddress>abc@gmail.com</EmailAddress>" | tr ">" "\n" | tr "<" "\n" | grep "@" | wc -c`
14

Note that I am off by one character as the echo gives a new-line.
Thus...

Code:

> echo `echo "<EmailAddress>abc@gmail.com</EmailAddress>" | tr ">" "\n" | tr "<" "\n" | grep "@" | wc -c` -1 | bc
13

or

Code:

> echo "<EmailAddress>abc@gmail.com</EmailAddress>" | tr ">" "\n" | tr "<" "\n" | grep "@" | tr -d "\n" | wc -c
13

but if we dont know what is there in between tags then how can we do means if we dont know/we didnt see the email id which is in between tags

for ex: EmailAddress>-------</EmailAddress>" in this ---- is nothing but some email id
