pure info: myjob-relaed_rawmaterila Timings: Full pure info: Check-platform-Log-90Days Timings: Full Timings: Incremental pure info: Check-vitorydows-Log-90Days Timings: Full Timings: Incremental pure info: Note_michael Timings: Full pure info: adhoc-activity-myjob-platform Timings: Full pure info: adhoc-activity-myjob-vitory Timings: Full pure info: adhoc-myjob-platform-03 Timings: Full Timings: Full-1month pure info: adhoc-onetime-myjob-hotcase Timings: Full pure info: adhoc-onetime-myjob-platform
需要輸出
pure info: myjob-relaed_rawmaterila Timings: Full pure info: Check-platform-Log-90Days Timings: Full Timings: Incremental pure info: Check-vitorydows-Log-90Days Timings: Full Timings: Incremental pure info: Note_michael Timings: Full pure info: adhoc-activity-myjob-platform Timings: Full pure info: adhoc-activity-myjob-vitory Timings: Full pure info: adhoc-myjob-platform-03 Timings: Full Timings: Full-1month pure info: adhoc-onetime-myjob-hotcase Timings: Full
我試過了
cat file1|sed -e 's/^ //' -e 's/$// cat file1|perl -pe's/\n/ / if $. % 3'
但這僅在一行中列印 2 行,如果有額外的
Timings
條目,那麼這就是鋸齒形輸出。我怎麼解決這個問題?
關於您的 perl 解決方案:由於 -p 構造,提供的腳本逐行處理輸入。這使得連接線變得困難,因為線不知道接下來會發生什麼。
當您將輸入作為一個字元串處理時,您可以執行智能替換來連接行。這是一個類似於您呼叫 perl 的方式的範例:
perl -e 'local $/;my $data = <>; $data =~ s/\nTiming/ Timing/g ; print $data' file1
此腳本讀取一個字元串 ($data) 中的整個輸入,並將 Timing 之前的換行符替換為空格。它適用於所有情況(替換後g切換為全域)
GNU sed 解決方案:
sed -rz 's/\n(Timings)/ \1/g' file1
