我有很長的字符串,我需要在時間戳的每個實例之前放置一個換行符。Sed腳本需要在每個時間匹配之前在一個大的單個字符串中插入LF
03:38:11,03/07/2017,node,cpu,user,sys,idle,intr/s,ctxt/s,0,0,0,9,91,0,1,0,24,75,0,total,0,17,83,2370,3574,1,0,3,4,
93,1,1,10,4,86,1,total,7,4,89,2922,4653,03:39:11,03/07/2017,node,cpu,user,sys,idle,intr/s,ctxt/s,0,0,4,25,71,0,1,5
,16,79,0,total,4,21,75,2487,3876,1,0,0,3,97,1,1,1,1,98,1,total,1,2,98,2880,4728,03:40:11,03/07/2017,node,cpu,user,
sys,idle,intr/s,ctxt/s,0,0,1,30,69,0,1,1,30,69,0,total,1,30,69,3237,4344,1,0,3,49,47,1,1,10,47,43,1,total,6,48,45,
3920,5702,
我需要看到格式化它是這樣:
03:38:11,03/07/2017,node,cpu,user,sys,idle,intr/s,ctxt/s,0,0,0,9,91,0,1,0,24,75,0,total,0,17,83,2370,3574,1,0,3,4,93,1,1,10,4,86,1,total,7,4,89,2922,4653,
03:39:11,03/07/2017,node,cpu,user,sys,idle,intr/s,ctxt/s,0,0,4,25,71,0,1,5,16,79,0,total,4,21,75,2487,3876,1,0,0,3,97,1,1,1,1,98,1,total,1,2,98,2880,4728,
03:40:11,03/07/2017,node,cpu,user,sys,idle,intr/s,ctxt/s,0,0,1,30,69,0,1,1,30,69,0,total,1,30,69,3237,4344,1,0,3,49,47,1,1,10,47,43,1,total,6,48,45,3920,5702,
我目前正在使用下列內容:
sed -e 's/^[[:digit:]][[:digit:]]\:[[:digit:]][[:digit:]]/\n&/g' cpu.log
我也應該注意到,它確實在第一場比賽中放了一個LF,但是沒有後續的比賽。 –
'sed -E's /,([[:digit:]] [[:digit:]]:)/,\ n \ 1/g'cpu.log'可能是 –
