replacing with `pwd`

Shell Programming and Scripting
1

Hi E(uni)xperts,

I have a file in which I need to replace some text with the current path of the execution.

meaning..

if I am running from

/user/oldtrash/scripts and the file contains

"this is ur directory current_dir"

then I should see the file content as

"this is ur directory /user/oldtrash/scripts"

Any ideas?

Thanks,
OldTrash

you answered your own question in the subject of this thread.

just make that text file executable.

Hi Optimus,
Thanks for the reply.
I forgot to mention my trials with sed and perl..

I tried

old>sed -e "s/current_dir/`pwd`/" < old_file > new_file
sed:command garbled: /current_dir//user/oldtrash/scripts/

old>perl -e "s/current_dir/`pwd`/" < old_file > new_file
Bareword found where operator expected at -e line 1, near "s/current_dir//user"
syntax error at -e line 1, near "s/current_dir//user"
Bareword found where operator expected at -e line 1, near "Oldtrash"
(Missing operator before Oldtrash?)
Execution of -e aborted due to compilation errors.

:confused:

why don'T you use the shell variable:

$PWD

?

i thought you ment you already had in place of current_dir teh pwd command.

didnt know you were trying to sub it on the fly.

dont use the forward slash in your sed command choose another metachar like pipe.

ie: sed "s|current_dir|`pwd`|" <filename>

that works on my sys
