You can covert perl script into ELF binary files, c source code, bytecode etc. You do this my using perlcc.
You can have list of examples by just
But here, i gonna only show you few. First let us generate a perl script, create a file call hello
#!/usr/bin/perl print "hello world. ";
Convert it into executable,
chmod +x hello
Try to run it, that is our normal perl script.
To make it as a binary with ELF header, do this
perlcc -o hello-bin hello
So what is the different? Check with file command,
hello: perl script text executable hello-bin: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped
File shows that “hello” is perl script, where “hello-bin” is a ELF executable binary file.
Usually if you want to do a single line perl, you do this
perl -e 'print "hello world. " '
Now same thing, if you want to convert a single line perl to bin, you do this
perlcc -e 'print "hello world. " ' -o hello-bin
