Custom bash_profile for Advanced Shell Users

Custom bash_profile for Advanced Shell Users

« An AskApache Plugin Upgrade to Rule them Allmod_rewrite Fix for Caching Updated Files »

Looking for some advanced uses for the shell? Function examples? Advanced shell settings? Here is some of my best.

Want to get started without even having to read this page? Type the following in your shell.

curl -O http://z.askapache.com/askapache-bash-profile.txt && source askapache-bash-profile.txt

For those of you power users and server admins that use Bash, ksh, csh, vanilla sh, etc.., or if you are just passionate about shell scripting, because it allows you to get advanced tasks done fast and efficiently, not to mention automated automatically. I give you my .bash_profile file. You should edit it to fit your needs, (especially the exported vars like PATH, LDFLAGS, if you don’t understand something just comment it out) but it’s pretty universal because I work on alot of other people’s servers not to mention many different distros and platforms, and when I get hired to do some server work through a shell, I bring this script along for the ride.

askapache-bash-profile.txt

You can download the latest version: http://z.askapache.com/askapache-bash-profile.txt

The functions and variables below are the way bash sees them, using declare -f, and alias, to make it easier for you to read and understand them. The actual file at http://z.askapache.com/askapache-bash-profile.txt will always be the most updated version, as I use it personally. And it has the whole file the way I wrote it, meaning many extra notes and much simpler to follow. Enjoy!

#!/bin/bash
#
# To install the latest version
#
# curl -O http://z.askapache.com/askapache-bash-profile.txt && source askapache-bash-profile.txt
#
# To run automatically at login: In your ~/.bash_profile or similar login script do
# [[ -r path-to-askapache-bash-profile.txt ]] && source path-to-askapache-bash-profile.txt

# cdable_vars             an argument to the cd builtin command that is not a directory is assumed to be the name of a variable dir to change to.
# cdspell                 minor errors in the spelling of a directory component in a cd command will be corrected.
# checkhash               bash checks that a command found in the hash table exists before execute it.  If no longer exists, a path search is performed.
# checkwinsize            bash checks the window size after each command and, if necessary, updates the values of LINES and COLUMNS.
# cmdhist                 bash attempts to save all lines of a multiple-line command in the same history entry.  Allows re-editing of multi-line commands.
# dotglob                 bash includes filenames beginning with a `.' in the results of pathname expansion.
# execfail                a non-int shell will not exit if it cannot execute the file specified as an argument to the exec builtin command, like int sh.
# expand_aliases          aliases are expanded as described above under ALIASES.  This option is enabled by default for interactive shells.
# extglob                 the extended pattern matching features described above under Pathname Expansion are enabled.
# histappend              the history list is appended to the file named by the value of the HISTFILE variable when shell exits, no overwriting the file.
# hostcomplete            and readline is being used, bash will attempt to perform hostname completion when a word containing a @ is being completed
# huponexit               bash will send SIGHUP to all jobs when an interactive login shell exits.
# interactive_comments    allow a word beginning with # to cause that word and all remaining characters on that line to be ignored in an interactive shell
# lithist                 if cmdhist option is enabled, multi-line commands are saved to the history with embedded newlines rather than using semicolon
# login_shell             shell sets this option if it is started as a login shell (see INVOCATION above).  The value may not be changed.
# mailwarn                file that bash is checking for mail has been accessed since the last checked, ``The mail in mailfile has been read'' is displayed.
# no_empty_cmd_completion bash will not attempt to search the PATH for possible completions when completion is attempted on an empty line.
# nocaseglob              bash matches filenames in a case-insensitive fashion when performing pathname expansion (see Pathname Expansion above).
# nullglob                bash allows patterns which match no files (see Pathname Expansion above) to expand to a null string, rather than themselves.
# progcomp                the programmable completion facilities (see Programmable Completion above) are enabled.  This option is enabled by default.
# promptvars              prompt strings undergo variable and parameter expansion after being expanded as described in PROMPTING above.
# shift_verbose           the shift builtin prints an error message when the shift count exceeds the number of positional parameters.
# sourcepath              the source (.) builtin uses the value of PATH to find the directory containing the file supplied as an argument.
# xpg_echo                the echo builtin expands backslash-escape sequences by default.

# history setup
#------------------------------------------------------------------------------------------------------------------------------------------------------------
# HISTCONTROL
#    If  set  to a value of ignorespace, lines which begin with a space character are not entered on the history list.
#    If set to a value of ignoredups, lines matching the last history line are not entered.  A value of ignoreboth combines the two options.
#    If unset, or if set to any other value than those above, all lines read by the parser are saved on the history list, subject to the value of HISTIGNORE.
# HISTFILE
#    The name of the file in which command history is saved (see HISTORY below).  The default value is ~/.bash_history.  If unset, the command history is not saved when an interactive shell exits.
# HISTFILESIZE
#    The  maximum number of lines contained in the history file.  When this variable is assigned a value, the history file is truncated, if necessary, to contain no more than that number of lines.
#    The default value is 500.  The history file is also trun-cated to this size after writing it when an interactive shell exits.
# HISTIGNORE
#    A colon-separated list of patterns used to decide which command lines should be saved on the history list.  Each pattern is anchored at the beginning of the line and must match the complete line (no implicit `*' is appended).
#    Each pattern is  tested against  the  line  after  the  checks  specified  by HISTCONTROL are applied.  In addition to the normal shell pattern matching characters, `&' matches the previous history line.
#    `&' may be escaped using a backslash; the backslash is removed before attempting a match.  The second and subsequent lines of a multi-line compound command are not tested, and are added to the history regardless of the value of HISTIGNORE.
# HISTSIZE
#    The number of commands to remember in the command history (see HISTORY below).  The default value is 500.
