simple question

[hokky]

Hi guys
here's my code

NUMBER=`ls Run_*.flag | wc -l`

echo "BATCH_$NUMBER"

let's say the flag file is 7
The result is BATCH_ 7

I want the result is BATCH_7

I have the way like this but I don't like it
NUMBER=`ls Run_*.flag | wc -l | awk '{print $1}'`

I was just wondering using eval or something which is more proper...
Thanks guys

Well , I'm not sure what's not to like.
NUMBER=`ls Run_*.flag | wc -l | awk '{print $1}'`


But if you are trying to get rid of the space between BATCH_ & 7.

The wc -l command puts the space in your answer. It's possible that washing the string back thorugh the shell interpreter via "eval" might remove the space, But I think using sed or awk (like you did aabove) is far more straight forward.

Something like this?

NUMBER=`ls Run_*.flag | wc -l`
(( NUMBER=NUMBER+0 ))

echo "BATCH_$NUMBER"

HTH,

Another way:

NUMBER=`ls Run_*.flag | awk 'END{print NR}'`
echo "BATCH_$NUMBER"

Hope This Helps, PH.

Another way in Korn Shell...

typeset -i NUMBER=$(ls Run_*.flag | wc -l)

echo "BATCH_$NUMBER"

The "[tt]typeset -i[/tt]" makes the variable an Integer which can have no spaces.
