search messages matching a pattern

magrep [
-c | -q | -m max
] [
] [
] [
-a | -d
] header:regex [
msgs ...

magrep prints the names of files from the specified msgs if the value of header matches the POSIX Extended Regular Expression regex. (See mmsg(7) for the message argument syntax.)
If header is empty, magrep matches against the maildir flags of msgs.
If header is ‘*’, magrep searches for the pattern in any header.
If header is ‘/’, magrep searches any plain text parts of the msgs body.
If no msgs are specified and magrep is used interactively, the current sequence will be searched.
The options are as follows:
Search for regex in RFC 2822 address header parts only.
Only print a count of matching messages.
Decode the header according to RFC 2047 prior to searching.
Match regex case insensitively.
Do not show more than max matches.
Print each match only, not the entire line. This option is ignored if -c, -q or -v is specified.
Print the filename, the header and the matching line for each of the matched msgs. If -o is specified each match is printed, instead of the matching line. This option is ignored if -c, -q or -v is specified.
Quiet mode: do not print anything, quit as soon as possible.
Invert the match; print (or count) all files where regex does not match.

The magrep utility exits 0 on success, 1 if no match was found and >1 if an error occurs.
