Changing the file name to a different one using csh
I have a file name

Code:
n10-z30-dsr65-ndelt1.00-varp0.08-16x12drw-csq-msf.ps

and I want to remove the varp info tag to get

Code:
n10-z30-dsr65-ndelt1.00-16x12drw-csq-msf.ps

Trying to use tr, but when I tried replacing varp with ooo I am getting the results below:

Code:
echo "n10-z30-dsr65-ndelt1.00-varp0.08-16x12drw-csq-msf.ps" | tr 'varp' 'ooo'

n10-z30-dso65-ndelt1.00-oooo0.08-16x12dow-csq-msf.os

Using
Code:
echo "n10-z30-dsr65-ndelt1.00-varp0.08-16x12drw-csq-msf.ps" | awk '{gsub(/varp/,""); print}'

gives me

Code:
n10-z30-dsr65-ndelt1.00-0.08-16x12drw-csq-msf.ps

The problem is that I also want to remove the number 0.08

I have to get

Code:
n10-z30-dsr65-ndelt1.00-16x12drw-csq-msf.ps

tr replaces sets of single characters, not strings as such.

tr 'varp' 'abcd' replaces v with a, a with b, etc.

Use sed:
Code:
 ... | sed 's/varp/ooo/g'

or awk:
Code:
 ... | awk '{gsub ("varp","ooo"); print}'

Assuming the field is delimited by dashes, try
Code:
 ... | sed 's/varp[^-]*-//g'

Try this...
Code:
sh-3.1$ echo 'n10-z30-dsr65-ndelt1.00-varp0.08-16x12drw-csq-msf.ps' | sed 's/varp/ooo/;s/.08//'

Is .08 fixed?
