NAME

aegrep - print lines matching a pattern

SYNOPSIS

aegrep [ option... ] pattern
aegrep -Help
aegrep -VERSion

DESCRIPTION

The aegrep command is used to search the source files for lines containing a match to the given pattern. By default, aegrep prints the matching lines.

There is no need to name files on the command line, all the project and change source files are supplied automatically. All non‐source files are ignored.

Most of the grep(1) options are understood, in their long form.

OPTIONS

The following options are understood:

--After-Context=number

Print number lines of trailing context after matching lines. Places a line containing a group separator (--) between contiguous groups of matches.

--Before-Context=number

Print number lines of trailing context before matching lines. Places a line containing a group separator (--) between contiguous groups of matches.

--Byte-Offset

Print the 0‐based byte offset within the input file before each line of output.

-Change number

This option may be used to specify a particular change within a project. See aegis(1) for a complete description of this option.

--color

Surround the matched (non‐empty) strings, matching lines, context lines, file names, line numbers, byte offsets, and separators (for fields and groups of context lines) with escape sequences to display them in color on the terminal.

--Context=number

Print number lines of output context. Places a line containing a group separator (--) between contiguous groups of matches.

--Count

Suppress normal output; instead print a count of matching lines for each input file. With --invert-match option count non‐matching lines.

--extended-regexp

Interpret pattern as an extended regular expression.

--Files-With-Matches

Suppress normal output; instead print the name of each input file from which output would normally have been printed. The scanning will stop on the first match.

--Files-WithOut-Matches

Suppress normal output; instead print the name of each input file from which no output would normally have been printed. The scanning will stop on the first match.

--fixed-strings

Interpret pattern as a list of fixed strings, separated by newlines, any of which is to be matched.

-Help

This option may be used to obtain more information about how to use the aegrep program.

--Ignore-Case

Ignore case distinctions in both the pattern and the source files.

--Invert-Match

Invert the sense of matching, to select non‐matching lines.

--Initial-Tab

Make sure that the first character of actual line content lies on a tab stop, so that the alignment of tabs looks normal.

--Line-Buffered

Use line buffering on output.

--Line-Number

Prefix each line of output with the 1‐based line number within its input file.

--Line-Regexp

--Maximum-Count=number

Stop reading a file after number matching lines.

--no-messages

Suppress error messages about nonexistent or unreadable files.

--Only-Matching

Print only the matched (non‐empty) parts of a matching line, with each such part on a separate output line.

--Perl-Regexp

Interpret pattern as a Perl regular expression.

-Project name

This option may be used to select the project of interest. When no -Project option is specified, the AEGIS_PROJECT environment variable is consulted. If that does not exist, the user's $HOME/.aegisrc file is examined for a default project field (see aeuconf(5) for more information). If that does not exist, when the user is only working on changes within a single project, the project name defaults to that project. Otherwise, it is an error.

--Unix-Byte-Offset

Report Unix‐style byte offsets.

--Word-Regexp

Select only those lines containing matches that form whole words. The test is that the matching substring must either be at the beginning of the line, or preceded by a non‐word constituent character. Similarly, it must be either at the end of the line or followed by a non‐word constituent character. Word‐constituent characters are letters, digits, and the underscore.

See also aegis(1) for options common to all aegis commands.

All options may be abbreviated; the abbreviation is documented as the upper case letters, all lower case letters and underscores (_) are optional. You must use consecutive sequences of optional letters.

All options are case insensitive, you may type them in upper case or lower case or a combination of both, case is not important.

For example: the arguments “-project”, “-PROJ” and “-p” are all interpreted to mean the -Project option. The argument “-prj” will not be understood, because consecutive optional characters were not supplied.

Options and other command line arguments may be mixed arbitrarily on the command line, after the function selectors.

The GNU long option names are understood. Since all option names for aegrep are long, this means ignoring the extra leading '-'. The “--option=value” convention is also understood.

EXIT STATUS

The aegrep command will exit with a status of 1 on any error. The aegrep command will only exit with a status of 0 if there are no errors.

ENVIRONMENT VARIABLES

See aegis(1) for a list of environment variables which may affect this command. See aepconf(5) for the project configuration file's project_specific field for how to set environment variables for all commands executed by Aegis.
