How to convert bash scripts into binary's, so no one can read it

[Aneesh Mohan]

Hi Dennis ,

I tried to do using ansi c too ,

# echo $CC
/opt/ansic/bin/cc
# ldd /opt/ansic/bin/cc
libstd.so.1 => /usr/lib/hpux32/libstd.so.1
libstream.so.1 => /usr/lib/hpux32/libstream.so.1
libCsup.so.1 => /usr/lib/hpux32/libCsup.so.1
libm.so.1 => /usr/lib/hpux32/libm.so.1
libunwind.so.1 => /usr/lib/hpux32/libunwind.so.1
libc.so.1 => /usr/lib/hpux32/libc.so.1
libdl.so.1 => /usr/lib/hpux32/libdl.so.1
libuca.so.1 => /usr/lib/hpux32/libuca.so.1
libdl.so.1 => /usr/lib/hpux32/libdl.so.1
# make cleanall
rm -f *.o *~ *.x.c
rm -f shc *.x

Edited Makefile :-

Comment out all the CFLAGS line except the below

# For HPUX
CFLAGS = -Ae -O +wlint

#make test


"shc.c", line 715, procedure do_all: warning #20202-D: Allocated memory may
potentially be leaked (at line 962)

*** Compiling script "match"
CFLAGS="-Ae -O +wlint" ./shc -v -f match
shc shll=sh
shc [-i]=-c
shc [-x]=exec '%s' "$@"
shc [-l]=
shc opts=
shc: /opt/ansic/bin/cc -Ae -O +wlint match.x.c -o match.x
"match.x.c", line 284: error #2165: too few arguments in function call
mine = !ptrace(PTRACE_ATTACH, pid, 0, 0);
^

1 error detected in the compilation of "match.x.c".
./shc: Error 0
*** Error exit code 1

Stop.

Thanks,
Abi

Now that you are using a real compiler, it is obvious. You are hosed. You can't use ptrace on IPF since ptrace isn't supported. You must port to ttrace(2) instead.
http://docs.hp.com/en/B2355-60130/ttrace.2.html

>ME: If this is ptrace(2), this isn't supported on IPF. See the man page.

Hi Everyone!

I find a fix for shc ..

# export CC=/usr/local/bin/gcc

# ldd /usr/local/bin/gcc

make test
make strings
make install
***     Installing shc and shc.1 on /usr/local
-n ***  ¿Do you want to continue?
y
        install -c -s shc /usr/local/bin/
install: The -c, -f, -n options each require a directory following!
*** Error exit code 2
And this error is removed when executing these 2 commands manually (I need to put the DIR after the -c:)

# /usr/sbin/install  -c /usr/local/bin/ -s shc /usr/local/bin/

# /usr/sbin/install -c /usr/local/bin/ -m 644 shc.1 /usr/local/man/man1/

and the executable is installed by you!! :

/usr/local/bin/shc

# file /usr/local/bin/shc

/usr/local/bin/shc:     ELF-32 executable object file - IA64

example of usage:
shc -r -T -f myscript.sh

And generates the executable:

myscript.sh.x

Kind Regards.   !
