| Doc Text: |
Cause:
Grep update fixed old bug regarding '-r' switch which may lead to incompatibility with some old badly written scripts.
Consequence:
Previously 'grep -r PATTERN' wrongly read STDIN. After the grep update 'grep -r PATTERN' recursively scans current directory for files containing the PATTERN which is according to its documentation. This behavior may break some old badly written scripts.
Fix:
Backward compatibility environment variable GREP_LEGACY_R has been introduced, which if set to '1', causes grep to behave the old buggy way, otherwise the grep behaves the new way.
Result:
Now, if GREP_LEGACY_R environment variable is set to '1', 'grep -r PATTERN' reads STDIN, otherwise it recursively scans current directory for files containing the PATTERN.
