Re: [opensuse] bashscripting (?) help in working with text files

Mon, 21 Jan 2008, by physwalker@xxxxxxxxx:

Hello List!

Through many pains I got the text file with some data and for plotting
purposes I need to separate it into files... with minimal knowledge on bash
scripting I was thinking maybe you could help me to figure that out... (I
tried to sort that out by hand, but then realised it will probably take a
month...)

I have special lines in my text file so, I'd love to be able to script
something like this

read through lines
if come to the string "bla bla bla"{
take the number after ": " on that string and put in file
named "something"...

Can be done in different ways, of course.
With grep and cut:
grep "bla bla bla" file |cut -d: -f2 >> something

With awk:
awk -F: '/"bla bla bla"/ {print $2}' file >>something

with Bash:
OLDIFS=$IFS
IFS=:
while read Line;do
set -- $Line
case $1 in
"bla bla bla") echo $2 >>something ;;
esac
done <file
IFS=$OLDIFS
