I have a really easy problem that I am not able to solve quickly. I must extract a substring from something like this:
a="www.himom.com/byebye"
I want to retrieve this:
"/byebye"
Actually, I am able to retrieve
"www.himom.com" with
echo ${a%/*}
Any suggestions?
Try this:
echo /${a##*/}
It deletes the longest substring ending at '/'.
Try this:
a="www.himom.com/byebye"; echo "/${a##*/}"
To leave the slash in the string
shopt -s extglob
echo "${a##*([^/])}"
$ a="www.himom.com/byebye" | echo ${a##*m}
/byebye
I am a lazy guy.. Solution was:
${a##*/}
You can extract your desired substring with a regex:
a="www.himom.com/byebye"
echo `expr match "$a" '.*\(\/.*\)'`
