Next: Matching strings in a line and printing them
From: mrkramer on 17 May 2010 18:58 It is possible to change NR or FNR variable? After getline fuction (in while loop) I would like to return to previous line. example file: ----- 1.ok 2.ok 3.ok 4.ok 5.error 6.foo 7.bar 8.ok 9.ok 10.error foo bar 11.ok 12.ok 13.ok 14.ok 15.eroor 16.foo 17.bar 18.ok 19.ok ---------- expected result ------- 5.error 6.foo 7.bar 10.error foo bar 15.error 16.foo 17.bar --------

It works in this case, but I wrong described how exactly looks my logfile. My logfile has on begining of line time in format hhmmss. Following there is some entries and somewhare in line is ERROR. Next lines after ERROR has description that error but don't have hour on begining. No everyone error has description on next line. Next line after this sequence there might be entry with error or not. Of course every entry begins by time in hhmmss format. example file: -------- 112200.aaa.error foo bar 112201.aa.error 112202.bb.error 112203.ok 112204.ok 112205.ok 113201.aa.error aaa bbb sql-err 113504.error 113650.ok 114056.ok ------------- expected result: -------------- 112200.aaa.error foo bar 112201.aa.error 112202.bb.error 1132.aa.error aaa bbb aql-err 113504.error ---------------- Now I solved this using awk and functions built in this program, but I'm curious any other ideas how to achieve expected result.

It wasn't result any script. |
