I have a script I wrote a couple of weeks ago. Part of the script scans email files and returns IP addresses found in them. I did this with this command:
cat * | grep -Po "\[\d+\.\d+\.\d+\.\d+\]" It worked fine right up until this afternoon. Now I get this: [EMAIL PROTECTED] ~/spam $ cat * | grep -Po "\[\d+\.\d+\.\d+\.\d+\]" grep: The -P option is not supported [EMAIL PROTECTED] ~/spam $ AFAIK, the only thing I've done between when it worked this morning and when it didn't this afternoon is started an emerge -ND world on bullet. Has anyone experienced this? Should it go away on its own after the emerge finishes, or is this functionality that has been phased out? What can I do about it otherwise? -- gentoo-user@gentoo.org mailing list
