这是我的ps -ef

的输出

我正在尝试在每个进程的命令行中提取-f选项之后的第二列和路径的最后一个组件。

我正在使用以下代码进行清理：

ps -ef | grep logstash | grep -v grep| awk -F" " '{print "Logstash is running for " substr($NF,7,10) " & PID number is " $2 }'

看起来像这样：

Logstash is running for S/CF_STAGE.es.config & PID number is 72561  
Logstash is running for CSL_STAGE.es.config & PID number is 96424  
Logstash is running for E/SENSE_STAGE.es.config & PID  is  
Logstash is running for STAGE/SMARTSCAN_STAGE.es.co & PID number is 203513  
Logstash is running for .2.2/AERO_STAGE_es.config & PID number is 602508

现在的问题是我只想让它看起来像这样（只是主题名称和PID）：

Logstash is running for CF_STAGE & PID number is 72561  
Logstash is running for CSL_STAGE & PID number is 96424  
Logstash is running for SENSE_STAGE & PID number 136554  
Logstash is running for SMARTSCAN_STAGE & PID number is 203513  
Logstash is running for AERO_STAGE & PID number is 602508

Answer 1

如果你总是希望摆脱相同的文本块，那么你可以将输出到目前为止的几个sed：

ps -ef | grep logstash | grep -v grep |
awk -F" " '{print "Logstash is running for " substr($NF,7,10) " & PID number is " $2 }' |
sed 's/S\///g' | sed 's/\.es\.config//g' | sed 's/E\///g' |
sed 's/STAGE\///g' | sed 's/\.es\.co//g' | sed 's/\.2\.2//g'

我希望我没有错过任何东西。一般命令是

sed 's/SUBSTITUTE_THIS/WITH_THIS/g'

并且许多反斜杠只是为了逃避某些符号。

Answer 2

使用function可能。你可以试试这个命令。

ps -ef | grep logstash | grep -v grep| awk -F" " 'function subst(str){
    split(str, arr, "/") ;
    split(arr[5], arr2, ".") ;
    return arr2[1] }   {print "Logstash is running for " subst($NF) " & PID number is " $2 }'

通过这个你会得到这样的正确答案。

Logstash is running for CF_STAGE & PID number is 72561
Logstash is running for CSL_STAGE & PID number is 96424
Logstash is running for SENSE_STAGE & PID number is 136554
Logstash is running for SMARTSCAN_STAGE & PID number is 203513
Logstash is running for AERO_STAGE_es & PID number is 602508

Answer 3

使用split()

ps -ef | grep logstash | grep -v grep | awk -F" " '{split($NF, a, "/"); split(a[5], b, "."); print "Logstash is running for " b[1] " & PID number is " $2 }'
