when i execute a .ksh file (for example sh toto), i have error when executing commande contenning the caracter `.
Thanks!Can you provide an example, with a sample of your error output? What editor are you using to create these scripts? (Some - like my favourite, joe - use the backtick operator as a metacharacter.)Sh toto.txt
Please find below commands in toto file:

echo "toto"
export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
OSTYPE=`uname -s`
C=`echo "\c"`
N=`-n`

when the sh execute the line containning the left quote(`), whe have the error below:
C:\Temp>sh toto.txt
toto
[1] + Done(134) ?
3820 Abort toto.txt
[1] + Done(134) ?
4452 Abort toto.txt
[1] + Done(134) ?
4704 Abort toto.txt

Thanks!You posted: "when i execute a .ksh file (for example sh toto), "

By issuing the sh - it is a bash shell, not ksh (korn),

was that a TYPO in your post?I do have ksh.exe. Usually i use sh.exe to execute ksh scripts. It was working i dont know why now it not working any more.
I beleive that the error is due to my machine.
Because it works on another machine.
Thanks!You MUST have a non-STANDARD .profile or SOMETHING, because I've run the script with no problem - except for the obvious: '-n' isn't a command, so the last line of the script will fail.

Please show me the output of the command "sh --version". Then attach copies of "~/.profile" and "/etc/profile" (as a zip file).Hang on a minute - "sh.exe"? Are you doing this on a Windows system? If so, you can't expect standard Linux/Unix FEATURES (such as backticks) to work as normal.
