Applicable for: Wind River Linux 9
Component/s: Userspace
In WRLinux 8 project, we found our grep tool can not support -P parameter, which was used to support Perl regular expression.
The grep version in WRLinux 8 is 2.21, in it's release notes, it show -P still can be used.
But in WRLinux 4.3, the grep(2.5.1) can support -P parameter.
Build a WRLinux 8 x86 project, and step into $(prj_dir)/export/dist/bin
run the following command:
./grep.grep -o -P 'PATTERN' file
then it will show:
./grep.grep: support for the -P option is not compiled into this --disable-perl-regexp binary
In a WRLinux 4.3 project, the same command can work well.
