Sed command in file not working

lbauer · 04-02-2005, 04:02 PM

I've got a little sed project for class.

When I run
s/'somename at domain.edu'/'lbauer@domain,edu'/g

this works fine from the command line and the substitution is made. But when I run it from a script in a file it doesn't work -- there's no substitution.
I even made it the only line in the file, copied and pasted from the command
I ran at the command line.

Is there a difference between results when you run from the command line vs a command within a file? Most of my other commands seem to be working.

There should be no difference, please post your script to clarify.

btw, you don't need the
quote marks within the ///

Code:

#!/usr/bin/sed -f

s/somename at domain.edu/lbauer@domain,edu/g

it worked for me. usually when i write a sed script i dont use the shebang (#!). i just run it with

Code:

command_with_output | sed -f sed_script

but i got your simple substitution script to work for me, although my interpreter was not located at /usr/bin/sed, it was /bin/sed. it looked like

Code:

#! /bin/sed -f
s/search/replace/g

i just had to change the permissions to executable so i could use it. then i could pipe some output to it.

Code:

>ls -1
search
search.txt
search_this_file.txt

>ls | ./sed_script
replace
replace.txt
replace_this_file.txt

i guess you should check to make sure you've made the script executable, and that the shebang is right.

Code:

which sed

will tell you were the sed executable is located.

it's not a shebang!
it's a 'hash-ping'
