LINUX COMMANDS

 Commonly used for a long strings that are frequently used. Alias allows you to have a small more familiar command or name to execute a long string.

Linux Commad Options:

name Specifies the alias name.

command Specifies the command the name should be an alias for.

autoupdate [options] [file]

GNU autoupdate tool. Update the configure template file file, or configure.ac if no file is specified. This command is seldom invoked
manually. It is usually called automatically from other autoconf tools.

autoscan [options] [directory]

GNU autoscan tool. Create or maintain a preliminary configure.ac file named configure.scan based on source files in specified directory,
or current directory if none given. If a configure.ac file already exists, autoconf will check it for completeness and print suggestions
for correcting any problems it finds.

autoreconf [options]

GNU autoreconf tool. Update configure scripts by running autoconf, autoheader, aclocal, automake, and libtoolize in specified
directories and subdirectories. This command is seldom invoked manually. It is usually called automatically from other autoconf tools.

automake [options] [template_file]

GNU automake tool. Create GNUstandards-compliant Makefile.in files from Makefile.am template files and can be used to ensure
that projects contain all the files and install options required to be standards-compliant. Note that versions 1.4 and 1.6 differ enough
that many distributions include an automake14 package for backward compatibility.

autoheader [options] [template_file]

GNU autoheader tool. Generate a template file of C #define statements from m4 macros defined in template_file, if given, or in a
configure.ac or configure.in file in the current working directory. The generated template file is almost invariably called config.h.in.

autoconf [options] [template_file]

Generate a configuration script from m4 macros defined in template_file, if given, or in a configure.ac or configure.in file in the current working directory. The generated script is almost invariably called configure.

atrm [option] job [job...]

Delete jobs that have been queued for future execution. Same as at -d.

Linux Commad Options:

-V Print the version number and then exit.

atq [options]

List the user’s pending jobs, unless the user is a privileged user; in that case, list everybody’s jobs. Same as at -l, and related to batch
and atrm.

Options
-q queue

-V Print the version number.

atd options

System administration command. Normally started in a system startup file. Execute jobs queued by the at command.
