Hi,

I am trying to insert an executable string inside a sed command in the
hopes that it will work.

ie:

cat filename | sed -e 's/system/`uname -n`/g'

I want uname -n to execute but to no avail.
How do I do this ?
Or is there a better way ?

Thanks

Hi...

set sys=`uname -n `
unset noclobber
cat filename | sed 's/system/ ' "$sys " '/g' > filename

...should do the trick. You could stick it in a script.

Uh oh, don't redirect sed's output to the same file being cat-ed, or
it'll get clobbered. I shot myself in the foot like that before!!

Try double quotes

ie

cat filename | sed -e "s/system/`uname -n`/g"

Note that the "cat filename |" is wasteful; use this instead:

sed -e "s/system/`uname -n`/g" filename
