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\/\(\([:alnum:]+\)\/+\)//'

NAME
pwd - Return the absolute path of the current working directory SYNOPSIS
pwd _________________________________________________________________ DESCRIPTION
Returns the absolute path name of the current working directory. EXAMPLE
Sometimes it is useful to change to a known directory when running some external command using exec, but it is important to keep the appli- cation usually running in the directory that it was started in (unless the user specifies otherwise) since that minimises user confusion. The way to do this is to save the current directory while the external command is being run: set tarFile [file normalize somefile.tar] set savedDir [pwd] cd /tmp exec tar -xf $tarFile cd $savedDir SEE ALSO
