egrep — Search a file for a specified pattern
Format
Description
egrep [–bcilnqsvx] [–e pattern] ... [–f patternfile] ... [pattern] [file ...]
Note: The egrep utility is fully supported for compatibility with older UNIX systems.
However, it is recommended that grep –e be used instead because it may
provide greater functionality and is considered the standard for portable
UNIX applications as defined by POSIX.2 IEEE standard 1003.2-1992.
See grep.
env — Display or set environment variables for a process
Format
Description
Options
Examples
Localization
env [–i] [variable=value ...] [command argument ...]
env [–] [variable=value ...] [command argument ...]
If you enter env with no arguments, it displays the environment variable that it
received from its parent (presumably the shell).
Arguments of the form variable=value let you add new environment variables or
change the value of existing environment variables.
If you specify command, env calls command with the arguments specified with the
argument argument that appear on the command line, passing the accumulated
environment variable to this command. The command is run directly as a program
found in the search PATH, and is not interpreted by a shell.
In a doublebyte locale, environment variable values may contain doublebyte
characters. The equal sign (=) must be singlebyte.
env supports the following two options, both of which have the same effect.
–i Specifies that the environment variable inherited by env not be used.
– Specifies that the environment variable inherited by env not be used.
Compare the output of the following two examples:
env foo=bar env
env –i foo=bar env
env uses the following localization environment variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES
