[SOLVED] Help with sed 'd

DuskFall · 08-11-2011, 02:46 PM

This probably does have a very simple answer, but i am unable to find it on google or anywhere else for that matter... i have a file that contains a filepath

Code:

 /Users/DuskFall

and i wish to remove all the slashs and the word Users from it, leaving just DuskFall so i can pull it back into a variable for the next part of my script. Thanks in advance.
p.s. I know grep would help here, except that filename changes as my script runs

Code:

user@Desktop:~$ echo "/Users/DuskFall" |sed -e 's/\/.*\/\([a-zA-Z]\)/\1/g'
DuskFall
user@Desktop:~$

echo "/Users/DuskFall" | sed 's/^.*\/$.*$$/\1/'

DuskFall

or even easyer with basename

Code:

user@Desktop:~$ basename /Users/DuskFall
DuskFall
user@Desktop:~$

Hi,

the sed's do not really need the backreferences here:

Code:

$ echo '/from/dusk/till/dawn' | sed 's@.*/@@'
dawn

Alternatively - if you are using bash - you can pull the path as is into your variable and extract the interesting part as follows:

Code:

$ var='/from/dusk/till/dawn'
$ echo ${var/*\//}
dawn
