Ich versuche, die zweite Spalte und die letzte Komponente des Weges nach der -f Option in jedem Prozess der Befehlszeile zu extrahieren.

Ich verwende den Code es aufzuräumen:

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

, die wie folgt aussieht:

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 

Nun das Problem ist, ich will es nur so aussehen (nur der Name des Themas & 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

Verwenden 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

Wenn Sie immer erhalten möchten Befreien Sie sich von den gleichen Textblöcke, dann können Sie Ihre Ausgabe so weit in ein paar sed gerade Rohr:

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' 

ich vermisse ich nicht etwas Hoffnung. Der allgemeine Befehl ist

sed 's/SUBSTITUTE_THIS/WITH_THIS/g' 

und die vielen Schrägstriche sind nur bestimmte Symbole zu entkommen.

Answer 3

Mit function ist es möglich. Sie können mit diesem Befehl versuchen.

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 }' 

dadurch erhalten Sie die richtige Antwort wie folgt.

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
