Subject: [Q] Simple shell script problem??
We have Redhat As 3.4 install ed on server. I am
write i simple script and have problem happen.
The user login shell is : CSH
the program we try to ru will use : KSH
%pg test1.sh
#!/bin/sh
set -v
echo $SHELL
export ORACLE_SID = CULNX
%./test1.sh
echo $SHELL
/bin/csh
export ORACLE_SID = CULNX
./test1.sh: line 4: export: `=': not a valid
identifier
look like "#!/bin/sh" useless. Program still use
"csh" to run it.
Any ideal?
Thanks.

The SHELL variable will always have the pathname of your login shell if it
remains set, regardless of the current shell you're running. If the SHELL
variable is set, calling /bin/ksh will not change the value. If the SHELL
variable is unset, #!/bin/ksh will set the SHELL variable to /bin/sh. And
actually, if you use #!/bin/sh, the SHELL variable will be set to /bin/bash,
the Bourne Again SHell. Go figure.
To unset the SHELL variable, type:
unset SHELL
at a command prompt. After that, your script as it's written will probably
echo /bin/bash.
As alread mentioned by Mike Ault, remove the spaces on both sides of the =
sign.
