permission of a filename.sh is -rwxr-xr-x


./filename.sh -> command not found

sh filename.sh -> then success...

why is that so?
i suspect is the -rwxr-xr-x

in filename.sh check that the #! line points to sh

the #! tells what program to execute the script with...

if the path is wrong to sh simply change it to where sh is on your system..


/Peter

in myfilename.sh, the first line is #!/bin/csh

for Bourne Shell:

#!/bin/sh

for C-Shell:

#!/bin/csh

for Korn Shell:

#!/bin/ksh

for Perl:

#!/usr/um/bin/perl

and does /bin/csh exist on you system??

check it out!

Yls177,

The reason that the "sh filename.sh " works is because you are invoking the bourne shell. Remember "sh" is actually a command. Read the man on sh.

When you use ./filename.sh, You are trying to execute the file in the current directory using its internal scripting. You must have the shell you are invoking inside the script, in the /etc/shells file. If not your script will fail.
