[ Level 2 ] Ubuntu package install script.

I wrote an easy script for install Ubuntu packages.

#!/bin/bash

#
# This script is for install popular packages
#
#$: check package, if exists, skip the following prefix #^
#@: apt-get install packages
#!: unix command
#^@: apt-get install packages, depends on previous #$
#^!: unix command, depends on previous #$
#

showUsage() {
  cat <<EOF
Usage:
  $0
  $0 [package name]
Ex.
  $0
  $0 rdesktop
EOF
}

isPackageNotInstall() {
  dpkg -l $1 >/dev/null 2>&1
  if [ $? -eq 0 ]
  then
    echo "Package '$1' exists, skip it!"
    return 1
  else
    return 0
  fi
}

getContent() {
  declare -i begin
  declare -i end
  declare -i size
  begin=$1
  end=$2
  size=$end-$begin+1
  tail -n +$begin $0 | head -$size
}

getPackageName() {
  echo $1 | cut -d' ' -f2- | cut -d'#' -f1
}

getCommand() {
  echo "$line" | cut -d' ' -f2- | cut -d'#' -f1
}

die() {
  echo $1
  exit 1
}

aptGetInstall() {
  echo -n "Start install package '$@'..."
  apt-get -y install $@ && echo "OK" || die "FAIL"
}

commandExecute() {
  echo -n "Start execute command '$@'..."
  $@ && echo "OK" || die "FAIL"
}
