Hi
im creating lots of log files, Im writing a script to number them and scp them to a remote server,
the files need to be called 0001.log 0002.log etc etc
in my script I made a counter variable
$counter=00001
I tried adding a number to the variable like this
$counter=`echo "$counter + 1" | bc`
but this gives me 2 not 0002
i tried with perl also $counter++
does anyone know a simple way to imrement but keep the leding 0's ??
Thanks
Try this:
#! /usr/bin/ksh
typeset -Z4 number=0
while ((number<10)); do
((number=number+1))
echo $number
done
exit 0
I keep a list of all RFC's on my workstation for some idle reading, and use a script to diplay a topic for the number I supply. The format they're in is: rfc####.txt, where the extra spaces are padded by "0"'s. I came up with this simple little routine to pad the left side of the number with zero's until I get a total of 4 characters:
...
numcheck=$((`echo $num | wc -c` - 1))
until [ "$numcheck" = "4" ]; do
num="0${num}"
numcheck=$((`echo $num | wc -c` - 1))
done
rcfname=rfc${num}.txt
...
This may not be the best way to do it, but it works for my needs... Please post back if you want more help with this.
HTH
Wow, I like Perderabo's much better.... time to re-write rfc.sh! 
Thanks guys, my script works fine now
its was this command that I needed form your script
typeset -Z4 number=0
Livinfree, What exactly do you refer to as RFC's ??
Silly newbie question I guess
request for comment
I presume he means.
