Shell Programming and Scripting

Hi All,
I've been searching through existing post and have been able to find most of what I want but am still stuck...

I'm trying to get part of the current file name as a string. The file name is in the form of:

basefilename_xxx(...).sh

I need the bit xxx(...) and it varies in length.

So far I have:

Code:

File=`basename $0 | cut -c 13-16

Obviously this will only get the first 3 characters of what I want.

How do I get any amount of characters between the underscore and the period without the extension? awk, sed, grep?


Thanks in advance

Hi
Can you please give as an example string? Wanted to know how the (...) is there in the string?

Guru.

Sorry the (...) is my probably bad way of saying that it's varying length. So some examples would be:

basefilename_lengthone.sh
basefilename_lengththree.sh
basefilename_lengtheleven.sh
basefilename_fivehundredandfortyone.sh

Hi

Code:

basename basefilename_lengthone.sh .sh | sed 's/.*_//'

Guru.

a=fadfagr_whatiwant.sh
a=${a#*_}
a=${a%.*}

a is the variable

Code:

$ string=junk1_junk2_whatiwant.sh
$ echo ${string##*_}
whatiwant.sh
$ string=${string##*_}
$ echo ${string%.*}
whatiwant

Code:

[house@leonov] echo "basefilename_lengthone.sh" | awk -F "[_.]" '{print $2}'
lengthone
