The line
Code:
#!/bin/bash

is the so-called "shebang" line which tells the system what interpreter to run the script in. It's pretty much the same as the magic bytes in executable formats, like ".ELF" (UNIX) or "MZ" (Windows .exe). This was needed after other shells and interpreters came available other than just the Bourne Shell.

Your other errors probably stem from the sed commands, as probably starting with Korn Shell (which is the base for the POSIX standard shell) the commands for sed have to be passed as a single argument, but the shell splits arguments on spaces. So your first command should (as an example) be written as
Code:
sed -e 's/ -/ DOT./' ipc > raw

GIT-SH-I18N(1)                                                      Git Manual                                                      GIT-SH-I18N(1)

NAME

       git-sh-i18n - Git's i18n setup code for shell scripts

SYNOPSIS

       . "$(git --exec-path)/git-sh-i18n"

DESCRIPTION

       This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish
       scripts and/or are writing new ones.

       The 'git sh-i18n scriptlet is designed to be sourced (using .) by Git's porcelain programs implemented in shell script. It provides
       wrappers for the GNU gettext and eval_gettext functions accessible through the gettext.sh script, and provides pass-through fallbacks on
       systems without GNU gettext.

FUNCTIONS

       gettext
           Currently a dummy fall-through function implemented as a wrapper around printf(1). Will be replaced by a real gettext implementation in
           a later version.

       eval_gettext
           Currently a dummy fall-through function implemented as a wrapper around printf(1) with variables expanded by the git-sh-
           i18n--envsubst(1) helper. Will be replaced by a real gettext implementation in a later version.

GIT

       Part of the git(1) suite
