Shell Programming and Scripting

Hello All,

I am here again scratching my head on pattern selection with special characters.


I have a large file having around 200 entries and i have to select a single line based on a pattern.

I am able to do that:

Code:

Code:

 
cat mytest.txt | awk -F: '/myregex/ { print $2}'

Output is as below:

Code:

 
//mytestserver.bon.com

now i have to split this output and pass only to a variable

i am trying this sed command ..but somehow this is not solving the purpose.

Any help where i am going wrong

Code:

 
cat mytest.txt | awk -F: '/myregex/ { print $2}' | sed 's/^[/  ^.]//'

Thanks
Usha

Please post the line from the input file that you're interested in.

Code:

echo '//mytestserver.bon.com' | sed -r 's //([^.]*).* \1 '
mytestserver

No need to cat mytest.txt...

Code:

awk -F: '/myregex/ { print $2}' mytest.txt | sed 's;/\{1,\};;'

Code:

awk -F"[:/]" '/myregex/ { print $(NF-2)}' mytest.txt

Hi,
Try this,

Code:

awk -F: '/myregex/ {gsub(/\//,"",$2);split($2,a,"."); print a[1];}' input_file

cheers,

Thanks Ranga.. Its perfect...

Cheers,
Usha
