From e9a910b33c7837b4b868e3abda18eb4810df7f02 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 4 Oct 2025 09:14:33 +0100 Subject: config/git: import suckless sbase i currently use the output of sha512sum in several places of xbmk, which is a bit unreliable in case output changes. other cases where i use util outputs in variables are probably reliable, because i'm using mostly posix utilities in those. to mitigate this, i now import suckless sbase, which has a reasonable sha512sum implementation. *every* binary it builds is being placed in build.list, because i'll probably start using more of them. for example, i may start modifying the "date" implementation, adding the GNU-specific options that i need as mentioned on init.sh i'm importing it in util/ because the sha512sum util is needed for verifying project sources, so if sbase itself is a "project source", that means we can into a chicken and egg bootstrapping problem. this is sbase at revision: 055cc1ae1b3a13c3d8f25af0a4a3316590efcd48 Signed-off-by: Leah Rowe --- util/sbase/grep.1 | 94 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 94 insertions(+) create mode 100644 util/sbase/grep.1 (limited to 'util/sbase/grep.1') diff --git a/util/sbase/grep.1 b/util/sbase/grep.1 new file mode 100644 index 00000000..9de0294a --- /dev/null +++ b/util/sbase/grep.1 @@ -0,0 +1,94 @@ +.Dd October 8, 2015 +.Dt GREP 1 +.Os sbase +.Sh NAME +.Nm grep +.Nd search files for patterns +.Sh SYNOPSIS +.Nm +.Op Fl EFHchilnqsvx +.Op Fl e Ar pattern +.Op Fl f Ar file +.Op Ar pattern +.Op Ar file ... +.Sh DESCRIPTION +.Nm +searches the input files for lines that match the +.Ar pattern , +a regular expression as defined in +.Xr regex 7 or +.Xr re_format 7 . +By default each matching line is printed to stdout. +If no +.Ar file +is given +.Nm +reads from stdin. +.Sh OPTIONS +.Bl -tag -width Ds +.It Fl E +Match using extended regex. +.It Fl F +Match using fixed strings. +Treat each pattern specified as a string instead of a regular +expression. +.It Fl H +Prefix each matching line with its filename in the output. +This is the default when there is more than one file specified. +.It Fl c +Print only a count of matching lines. +.It Fl e Ar pattern +Specify a pattern used during the search of the input: an input +line is selected if it matches any of the specified patterns. +This option is most useful when multiple -e options are used to +specify multiple patterns, or when a pattern begins with a dash. +.It Fl f Ar file +Read one or more patterns from the file named by the pathname file. +Patterns in file shall be terminated by a . +A null pattern can be specified by an empty line in pattern_file. +Unless the -E or -F option is also specified, each pattern shall be +treated as a BRE. +(`-'). +.It Fl h +Do not prefix each line with 'filename:' prefix. +.It Fl i +Match lines case insensitively. +.It Fl l +Print only the names of files with matching lines. +.It Fl n +Prefix each matching line with its line number in the input. +.It Fl q +Print nothing, only return status. +.It Fl s +Suppress the error messages ordinarily written for nonexistent or unreadable +files. +.It Fl v +Select lines which do +.Sy not +match the pattern. +.It Fl w +The expression is searched for as a word (as if surrounded by '\\<' and '\\>'). +.It Fl x +Consider only input lines that use all characters in the line excluding the +terminating to match an entire fixed string or regular expression to +be matching lines. +.El +.Sh EXIT STATUS +.Bl -tag -width Ds +.It 0 +One or more lines were matched. +.It 1 +No lines were matched. +.It > 1 +An error occurred. +.El +.Sh SEE ALSO +.Xr sed 1 , +.Xr re_format 7 , +.Xr regex 7 +.Sh STANDARDS +POSIX.1-2013. +.Pp +The +.Op Fl Hhw +flags are an extension to that specification. -- cgit v1.2.1
