quick question about sed pls... 2

[h3nd]

Hi guys,

I just wanna remove the last instance (*) of value :

the original value is :
*generic.sh*5*

I have tried :
echo "*generic.sh*5*" | sed -e 's/\*//'

But it didnt work, any idea ??

Thanks,

 

[PHV]

you wanted this ?
echo "*generic.sh*5*" | sed -e 's/\*[!]$[/!]//'

Hope This Helps, PH.

Thx PHV,

but what about using awk, because what I'm doing like this :

echo "[Nov 09 10:10:31] DONE[1] := 1 := *generic.sh*5*" | awk -F ":=" '{print $3}' | sed 's/\*//1;s/\*$//'

I want to remove the first instance and last instance,
so if I can use awk, that would be neater script..

Thx man

Like this ?
awk -F ":=" '{x=$3;sub(/\*/,"",x);sub(/\*$/,"",x);print x}'

Hope This Helps, PH.

Hi PHV,

one more question:

what about I wanna remove second and the last :
I've tried this doesnt work

awk -F ":=" '{x=$3;gensub(/*/,"",2,x);sub(/*$/,"",x);print x}'

Thanks man

Unlike sub() and gsub(), the modified string is returned as the result of the function, and the original target string is not changed.

So this should work as expected:

awk -F ":=" '{x=gensub(/*/,"",2,$3);sub(/*$/,"",x);print x}'
