New revision: 363381
URL: https://svnweb.freebsd.org/changeset/base/363381
Log:
Fix some regressions with the zgrep(1) wrapper.
- 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.
