Given:
$ cat test.ksh
doit()
doi1()
echo doi1 "$@"
doi2()
echo doi2 "$@"
doi1 a
doi2 b
doit
functions doit
typeset -f doit
Why do I get this output (doi2() and the last } are missing):
$ perl -e '$a=join("",<>);system("ksh","-c",$a)' test.ksh
doi1 a
doi2 b
doit() {
doi1()
echo doi1 "$@"
echo doi2 "$@"
doit()
doi1()
echo doi1 "$@"
echo doi2 "$@"
and not this:
doi1 a
doi2 b
doit()
doi1()
echo doi1 "$@"
doi2()
echo doi2 "$@"
doi1 a
doi2 b
doit()
doi1()
echo doi1 "$@"
doi2()
echo doi2 "$@"
doi1 a
doi2 b
Is there any way I can tell ksh to leave the function names untouched and thus give me the full function definition?

FWIW, you'll get the same behaviour withksh93 -c "$(cat test.ksh)".

@Kusalananda Yes. That is an even simpler example.

Strange bug. It seems to be triggered by ksh not having a script name:ksh <test.kshhas the same effect. It's not due to having multiple function definitions: the display is cut off after the end of the definition ofdoi1, except for any other nested function definition.

Can I set a (fake) script name? Somewhat similar to$0="myname"in perl?
