[solved] remove pattern with sed

Hi,

i want to remove a certain pattern when i type pwd.

pwd will look like this:

..../....../....../Pat_logs/..../....../...../......

the dotted lines are just random directory names,
i want it to remove the "Pat_logs/...../....../....../" part

so for example:

a/b/c/d/Pat_logs/e/f/g

will become:

a/b/c/d/g

thanks!

I got this... but apparently it does nothing, so I don't think it finds the pattern correctly.

pwd | sed 's/\/PAT_logs\/\(\([:alnum:]+\)\/+\)//'

Hi.

PAT_logs is not the same as Pat_logs. Sed like most everything in Unix is case-sensitive.

Code:
$ echo a/b/c/d/Pat_logs/e/f/g | sed 's/\/*Pat_logs.*\//\//'
a/b/c/d/g

Yes, everything should be PAT_logs, I just typed the post in the wrong case sorry.

Did you actually test that?

Code:
$ echo a/b/c/d/PAT_logs/e/f/g | sed 's/\\PAT_logs//g'
a/b/c/d/PAT_logs/e/f/g

thanks scotnn. thanks.
Code:
echo "/a/bc/def/PAT_logs/g/hi/jkl/" | sed "sz/PAT_logszzg'

it's better:
Code:
echo "/a/bc/def/PAT_logs/g/hi/jkl/" | sed "sz/PAT_logszz'

output:
Code:
/a/bc/def/g/hi/jkl

You must have booted your computer with the --ultra-lax-syntax option, because works "less" than the last one Smilie
