Hello Omkar,

grep -v will remove the line completely if pattern is matched. We can take help for awk here.

Code:
lparstat -i | grep -w "Entitled Capacity" | awk 'gsub(/[a-zA-Z]/,X,$0) gsub(/[[:punct:]]/,Y,$0) {print $0}'


Thanks,
R. Singh

great but the output of the script as as below :

Code:
 
$ lparstat -i | grep -w "Entitled Capacity" | awk 'gsub(/[a-zA-Z]/,X,$0) gsub(/[[:punct:]]/,Y,$0)'
                            100
                      1900

i was looking to grep only the below line :

PHP Code:
Entitled Capacity                          : 1.00 
out of the below output :

PHP Code:
$ lparstat -i | grep -w "Entitled Capacity"
Entitled Capacity                          : 1.00
Entitled Capacity of Pool                  : 1900 
Could you guide me how can to do that...output should be:
Entitled Capacity : 1.00

script should search for pattern "Entitled Capacity" only.

please let me know how can this be achived .

Hello,

Following may help.

Code:
lparstat -i | grep -w "Entitled Capacity" | awk -F":" 'NR==1 {a=$1;gsub(/[[:space:]]/,X,a); {print a OFS $2}}'

EDIT:
for getting colon in output.

Code:
lparstat -i | grep -w "Entitled Capacity" | awk -F":" -vs1=" : " 'NR==1 {a=$1;gsub(/[[:space:]]/,X,a); {print a s1 $2}}'


Thanks,
R. Singh

Try :

Code:
$ lparstat -i | awk '/Entitled Capacity/ && NF==4{$1=$1;print}'

Tested like this
Code:
$ cat file
Entitled Capacity                          : 1.00
Entitled Capacity of Pool                  : 1900

$ awk '/Entitled Capacity/ && NF==4{$1=$1;print}' file
Entitled Capacity : 1.00
