-ef私のPSの出力です。

私はそれをクリーンアップするために以下のコードを使用しています。このようになります

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

：

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 

今の問題は、私はちょうどそれだけで（次のようになりたいですトピック名& 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

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 }' 

Answer 2

同じテキストブロックを取り除く、あなた、これまでのsedのカップルにちょうどパイプあなたの出力をすることができます：私は何かを逃さなかった願ってい

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' 

。 一般的なコマンドは

sed 's/SUBSTITUTE_THIS/WITH_THIS/g' 

であり、多くのバックスラッシュは、特定の記号をエスケープするだけです。

Answer 3

functionを使用すると可能です。このコマンドで試すことができます。

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 }' 

これで正しい答えが得られます。

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
