UNIX for Dummies Questions & Answers

Hi,

Can anyone tell me if I can apply multiple cut on a single variable like below in a sh script:

tmp=`cut -c 1-4 $val`
tmp1=`cut -c 5-12 $val`
tmp2=`cut -c 13-18 $val`

If not, what is the other way to do this.

Thanks and Best Regards

hi,
yes you can do it.
are you getting any problem

Gaurav

Yes Gaurav,

It is just assigning the value to 1st variable only.

Rest are ignored.

My code is as below, Forgive me if I am making a silly mistake as I am very new to UNIX scripting and just practicing some commands:

Code:

awk {'print $1'} filename | while read line
do 
val=$1
tmp=`cut -c 1-4 $val`
tmp1=`cut -c 5-12 $val`
tmp2=`cut -c 13-18 $val`
echo $tmp $tmp1 $tmp2 >> tmpfile
done

In the tmpfile it is just giving 1st four characters from the variable.

Can you suggest what is wrong in it.

Thanks in advance.

Best Regards

Shoeb

use

and so on......
bye the way what exactly are you passing as the parameter($1)

Gaurav

Thanks Gaurav for your prompt reply,

I am sorry but I am not getting anything written in a tmpfile.

My parameter is looks like below:

192028/02/06226735

Please advise.

Best Regards

do the following things,

1) instead of redirecting it to tempfile, display the variables on terminal and see if they are getting displayed.
2) if the step 1 is not working then post your script and the output after running it using set -x.

Thanks Gaurav for your suggestions,

Thanks by the way for all your efforts.

Best Regards,
