perl one line for advanced grep (current line and next one)

[sroux]

Dear guruz, Is there any way of doing a one liner grep and displaying the matching lines but also the next line? > This would interests me (unix version with -A option) : $ grep -A1 error file test_log.txt I found this basic one liner grep : perl -nle "print if /error/" test_log.txt Many thanks for lightening my path.
