+ +

The `s6-grep` program

+ +

+ s6-grep matches its input against a pattern. +

+ +

Interface

+ +

+     s6-grep [ -E | -F ] [ -i ] [ -c ] [ -n ] [ -q ] [ -v ] pattern
+

+ +

s6-grep compiles pattern as an +Basic +Regular Expression
It reads stdin and matches every line against this regexp
If the line matches, it prints it to stdout
It exits on EOF with code 0 if one or more lines matched and 1 +otherwise.

+ +

Options

+ +

-F : pattern is not compiled as a BRE, but is +interpreted as a literal string.
-E : pattern is not compiled as a BRE, but as an +Extended +Regular Expression (ERE).
-i : ignore case during the match
-c : do not write normal output; only write the number of +lines that have matched pattern after EOF is received
-n : precede every output line by its number and a colon. +The first input line has number 1.
-q : do not write anything to stdout
-v : invert the pattern matching (select lines that do not +match pattern).

+ +

Posixness

+ +

+ s6-grep is not suitable as a Single Unix +grep +program. +
