pattern matching in Bash
- by Tim
Hi,
Here is an example to get different parts of a filename
bash-3.2$ pathandfile=/tmp/ff.txt
bash-3.2$ filename=$(basename $pathandfile)
bash-3.2$ echo $filename
ff.txt
bash-3.2$ echo ${filename##*.}
txt
bash-3.2$ echo ${filename%.*}
ff
I was wondering what does ## and % mean in the patterns. How is the patten matching working?
Thanks and regards!
