/usr/share

The /usr/share hierarchy is for all read-only architecture independent data files.

/usr/bin

Non-essential command binaries (not needed in single user mode); for all users.

make_wrapper <wrapper> <target> [chdir] [libpaths] [installpath]

Create a shell wrapper script named wrapper in installpath (defaults to the bindir) to execute target (default of wrapper) by first optionally setting LD_LIBRARY_PATH to the colon-delimited libpaths followed by optionally changing directory to chdir.

bindir

The directory for installing executable programs that users can run. This should normally be /usr/local/bin, but write it as $(exec_prefix)/bin. (If you are using Autoconf, write it as ‘@bindir@’.)

${string%substring}

Deletes shortest match of $substring from back of $string.

Some examples

#!/bin/sh 
prefix=/usr
exec_prefix=${prefix}

exec /usr/bin/mono /usr/lib64/pinta/Pinta.exe "$@"
