In more recent versions of the kornshell 93, there is the variable $.sh.fun which works with both the Posix- and the kornshell function syntax

Code:
#!/bin/ksh93

function f1
{
    print I am ${.sh.fun}
}

f2 ()
{
    print I am ${.sh.fun}
}

f1
f2

Output:

Code:
I am f1
I am f2

Thanks for all the tips, unfortunately none of them work for me. I think I'll just switch to bash.

Which OS (including version) and version of KSH are you using?

We asked if you could post your script, but you never did.

Probably Solaris <= 10.

Neither /bin/ksh nor /usr/xpg4/bin/sh process $0 in ksh-style functions correctly. Just checked.

I'm sorry, I didn't see that. I don't have a script, I was just testing it with a few small examples.

As for the version, I'm running SunOS 5.10 with ksh version M-11/16/88i.

I've just done a fresh install of Solaris 10, and it seems there is no ksh93 Smilie

Bash does have the $FUNCNAME variable, as said, but that's not a compelling enough reason (for me at least) to switch shells!

So your options appear to be: use Bash; install a newer ksh; set the name at the beginning of the function, as suggested; wait for someone who might know something we don't; write a wrapper:

Code:
$ cat myTest
#!/usr/bin/ksh

call() {
  FUNCNAME="$1"; shift
  "$FUNCNAME" "$@"
}

function f1
{
    echo "I am $FUNCNAME with $@ (${#@} arg(s))"
}

f2 ()
{
    echo "I am $FUNCNAME with $@ (${#@} arg(s))"
}

call f1 a b c "d e"
call f2 1 2

Code:
$ ./myTest
I am f1 with a b c d e (4 arg(s))
I am f2 with 1 2 (2 arg(s))

That's true. ksh93 was added to Opensolaris by the Korn Shell 93 integration/migration project and is the default kornshell in Solaris 11.

If you want to install ksh93 for Solaris <= 10, you can download prebuilt binaries as well as the source code from here
