What the command to find out the record length of a fixed length file?

I want to find out the record length of a fixed length file? I forgot the command. Any body know?
# 2  
Code:
awk '{print length;exit}' filename

in shell (bash, zsh, ksh93):

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

Hammer & Screwdriver Here is an approach

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
