sed command to remove a word from string

Shell Programming and Scripting
1

Hello All,
I am running a command

find . -name amp.cfg | cut -c 3-

which gives me output something like below

rel/prod/amp.cfg
rel/fld/amp.cfg
deb/detail/amp.cfg
deb/err/amp.cfg

              I want to remove trailing "/amp.cfg" so that i should get output something like below.

rel/prod
rel/fld
deb/detail
deb/err

.
I tried tr command

tr -d 'amp.cfg'

but had no luck.

Regards,
Anand Shah

Dear Pamu,
As I told in my post, i am using piped output from previous commands as input to sed so when i run this command it gives me No such file or directory error.

I also tried

sed `s/\/\amp.cfg$//`

"`" won't work here....

try

find . -name amp.cfg | cut -c 3- | sed 's/\/amp.cfg$//'

Dear Pamu,
Thank you.Its working fine.
I was using "`" instead of "'".My mistake.
Can u plz tell me the use of "$" as it is working fine without that ?

"$" denote for the end of the line

Below command is also another way to match your pattern

$ is used for a line which ends with amp.cfg.
Without using $ it will replace first entry of the line

Please check..

$ cat file
rel/prod/amp.cfg
rel/fld/amp.cfg
rel/fld/amp.cfg/sdd
rel/fld/amp.cfg/doc/cam/amp.cfg

$ sed 's/\/amp.cfg$//' file
rel/prod
rel/fld
rel/fld/amp.cfg/sdd
rel/fld/amp.cfg/doc/cam

$ sed 's/\/amp.cfg//' file
rel/prod
rel/fld
rel/fld/sdd
rel/fld/doc/cam/amp.cfg
