One quick way is to run the script with: ksh -x script_name
You may have to pipe through more to be able to "see" the lines. |

Be careful, though. At least Sun's Bourne shell prints set -x output to
stderr, so you might need to use ksh -x script_name 2>&1 | more

I beleive that goes for most shell's. The shell prompt also goes to
stderr. If you realy want to catch everything in a file I would recommend
using "script", and then display the "typescript" file afterwards.

OK, you probably want to start with limiting your cross posting. Many
newsreaders, servers, etc. will automatically kill messages with more than
xome arbitrary nubmer of newsgroups - usually 4 or 5. So crossposting to
a dozen groups will get you less distribution than more.
Also, pick your groups; ksh is not distributed with any linux distro that
I know of (and my knowledge is admittedly limited) because of its license.
But if you really want to know the answer to your question, I'd start with
http://www.kornshell.com/ . |

The pdksh is, however, and that may be close enough for some of us.

I can't test this, as I don't have access to a Linux machine right now,
but you might try this:
cat test.sh | tee /dev/tty | ksh -s
You might also consider creating a ~/bin/echosh script that embodies
the above functionality, and add...
#!/home/username/bin/echosh
....to the beginning of each script you want executed in that fashion. |

Re: Wanted: GNU utility (similar to sed) to edit text files directly.

Thanks everyone.
It's good to know that you cant edit a file directly without a filecopy occuring.
The rename instead of copy idea should help make my task more efficient.

make your shebang look like this:
#/bin/ksh -xv
where: -x print all commands incl. parms to stdout; vars are already
interpreted
-v print each line read to stdout
