Bash Script That Will Cut
The File Up
Question:
I have a file that has one line in it, and looks like
this:
Code:
-a test.example.com -a next.example.com -a last.example.comI'm
trying to code a bash script that will cut the file up, and only give me
the *.example.com portions. I imagine I'll need the cut command (or multiple
cut commands). Something like this:
Code:
list=`cat thefile | cut -d"-"I know that's not a working
example, but I wanted to see if anyone else had attempted something similar
before and could give me an example. The number of entries can be variable
and the domain names can of course be anything, but it will always be in
the same format and on one line.
Solutions:
Say for example
Code:
$ a="-a test.example.com -a next.example.com -a last.example.com"
$ set -- $(echo ${a//-a/})
$ echo $@
test.example.com next.example.com last.example.com
$ echo $1
test.example.com
$ echo $2
next.example.com
$ echo $3
last.example.comin a file
Code:
while read -r line
do
set -- ${line//-a/}
echo $1
echo $2
echo $3
done < "file"
PS: That will gets you running in the right direction.
I think, if you do not know the number of entries in the file, you can
play and get that from "echo $@" I think.
