- Handle whitespace with long flags that take arguments: echo 'foo bar' > test zgrep --regexp='foo bar' test - Do not hang reading from stdin with patterns in a file: echo foobar > test echo foo > pattern zgrep -f pattern test zgrep --file=pattern test - Handle any flags after -e: echo foobar > test zgrep -e foo --ignore-case < test These two are still outstanding problems: - Does not handle flags that take an argument if there is no whitespace: zgrep -enfs /etc/rpc - When more than one -e pattern used matching should occur for all patterns (similar to multiple patterns supplied with -f file). Instead only the last pattern is used for matching: zgrep -e rex -e nfs /etc/rpc (This problem is masked in the unpatched version by the "any flags after -e" problem.) Add tests for the above problems. Update the mange and add references to gzip(1) and zstd(1) and also document the remaining known problems.

This version of the
|
|
.Nm

|
utility was written by
|
|
.An Thomas Klausner Aq Mt wiz@NetBSD.org .
|
|
.Sh BUGS
|
|
.Xr zgrep 1
|
|
does not handle flags that take arguments if there is no whitespace
|
|
between the flag and the argument, for example:
|
|
.Pp
|
|
.Dl "zgrep -enfs /etc/rpc"
|
|
.Pp
|
|
When more than one
|
|
.Fl e
|
|
flag is used matching
|
|
should occur for any of the patterns (similar to multiple patterns
|
|
supplied in a file with the
|
|
.Fl f
|
|
flag).
|
|
.Xr zgrep 1
|
|
only matches the last
|
|
.Fl e
|
|
pattern.
