我有这样的输出:
TEXT
SOMETEXTELSE
我需要合并字符串,并在它们之间添加符号“ R”,例如:
TEXT R SOMETEXTELSE
我该怎么办?
谢谢
更新。抱歉。这是命令
egrep -B1 ELLDB@сranium.*FAILED /var/log/alert.log | tail -2
这是输出:
ERR-0045 Database is down for given SID. Can't perform backup.
2014-12-19 16:15:01 ELLDB@сranium Backuper:bkp status: FAILED 98456876
我需要像这样的输出:
ERR-0045 Database is down for given SID. Can't perform backup. R 2014-12-19 16:15:01 ELLDB@сranium Backuper:bkp status: FAILED 98456876
最佳答案
sed '$! s/.*/\0 R/' | paste -s -d " "
关于linux - 将两行合并为一个并添加字符,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/29437341/
