bash string processing

powah · 03-13-2007, 06:56 PM

If the bash input parameter $1 is in the format "xyznnnnn", where "xyz" is fixed and "nnnnn" can be varied, how to extract the remaining of the string "nnnnn"?
e.g.
If input is "xyzabc", then extracted string should be "abc".
If input is "xyz12345678", then extracted string should be "12345678".
Thanks in advance.

stripped_string=$(echo $1 | sed s/xyz//)

This is what I could do without looking it up in the Bash guide. Bash also has string functions. Take a look at the guide as pointed to in my signature.

Code:

bash-2.05$ x=xyz12345     
bash-2.05$ echo $x
xyz12345
bash-2.05$ echo ${x#xyz}
12345
