apropos

apropos string ...

Search the short manual page descriptions in the whatis database

for occurrences of each string and display the result on the stan-

dard output. Like whatis, except that it searches for strings instead

of words. Equivalent to man -k.

apt

apt

The Advanced Package Tool, the Debian package management

system. A freely available packaging system for software distribu-

tion and installation. For detailed information on apt and its

commands, see Chapter 5.

ar

ar key [args] [posname] [count] archive [files]

Maintain a group of files that are combined into a file archive. Used

most commonly to create and update static library files, as used by

the link editor (ld). Compiler frontends often call ar automatically.

Only one key letter may be used, but each can be combined with

additional args (with no separations between). posname is the name

of a file in archive. When moving or replacing files, you can specify

that they be placed before or after posname. ar has largely been

superseded by tar and bzip2.

Keys

d Delete files from archive.

m Move files to end of archive.

p Print files in archive.

q Append files to archive.

r Replace files in archive.

t List the contents of archive or list the named files.

x Extract contents from archive or only the named files.
