Read lines from script and add "echo" to it 3

[TSch]

Hi folks,

I'd like to create a little script that reads the lines from another script, changes them and writes them into a new file.

Something like that:

Sourcefile
----------
read input
find / -name $input
uname -a

Destination file is supposed to look like this:
-----------------------------------------------
echo "read input"
read input
echo "find / -name $input"
find / -name $input
echo "uname -a"
uname -a


Okay, maybe this is not the most elegant way to accomplish what I want, but it is the only way I can think of right now.

The goal is to change a script to echo the line that is being executed so that I can see where it hangs. I have a script that won't finish but is not giving me any errors and it's got way too many lines to change them all manually.

Any ideas what i could do here ?

Regards
Thomas

Hi

sed 'h;s/.*/echo "&"/;G' /old/file > /new/file

Tested with GNU [tt]sed[/tt].

Run the script with [tt]ksh -v /path/to/script[/tt], and you'll accomplish the same...

[p5wizard]

sometimes [tt]ksh -x[/tt] helps also

Or add

[tt]set -x
set -v[/tt]

in the beginning of your script...

And for set -x
add:
export PS4='${LINENO}:'
to see the line number that is executed
