how to set the shell to bash if there is bash otherwise set to ksh
I am in linux , aix , solaris
Usually there is bash on the box, sometimes not
if there is bash on the box, I want to run my scripts in bash.
if there is not bash on the box THERE WILL BE KSH and i would like to set my scripts to run
in ksh ( so it does not default to sh )
how can I do this ?

Omit the shebang line #!...
and call your script like
[[ -x /bin/bash ]] && INTP=/bin/bash || INTP=/bin/ksh; $INTP /path/to/script
If your default login shell is either bash or ksh then you can do
$SHELL /path/to/script
Here too you must omit #!...
and call your script like
[[ -x /bin/bash ]] && INTP=/bin/bash || INTP=/bin/ksh; $INTP /path/to/script
If your default login shell is either bash or ksh then you can do
$SHELL /path/to/script
Here too you must omit #!...
This is another trick.
Prefix your script (again without the shebang) with the following code (I took the first part from your other question):
function shellselect {
if [[ -e "/bin/bash" ]]; then
INTERP="/bin/bash"
else
INTERP="/bin/ksh"
fi; }
if [[ $1 != "12345selected54321" ]]; then
shellselect
$INTERP $0 "12345selected54321" "$@"
exit
else shift
fi
# actual code starts here, next two lines just for demonstration ...
echo $BASH # line will be empty if ksh is used, else it will contain the path to bash.
echo $@ # to show that the params are still there
# ....
# ....
