To extract the string between two patterns

Shell Programming and Scripting
1

Sample input:

Loading File System
Networking in nature

Closing the System

now i need to extract the patterns between the words File and Closing:

i.e. sample output:

System
Networking in Nature

Thanks in advance !!!!!!!!!!!!!!!!!

This is a bit clumsy but it seems to do what you want...

cat <file> | sed 's/.File //' | sed 's/Closing.$//'

yes indeed. you don't need the cat, and you can just use one sed command. Not very good with sed, but just an example.

sed -e 's/.*File //' -e 's/Closing.*$//' file

Thanks Guys !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

but if suppose i have an input like this:

Unix Shell scripting

Java Framework

Network Administrator

Perl Shell scripting

now i need to extract the patterns between "Java" and "Administrator"

so that my output should be

Framework

Network

5

one way

awk '/Java/{flag=1;}
    /Administrator/{print ;flag=0}
    flag { print }' "file"

i leave it to you to try remove "Java" and "Administrator"

U can also use sed:

sed -n "/Java/,/Administrator/p" file

Hi, you can try this one also:D.

awk 'BEGIN{f=0}
{
if (index($0,"File")!=0)
f=1
if (index($0,"Closing")!=0)
f=0
if (f==1)
{
if (index($0,"File")!=0)
printf("%s\n", substr($0,index($0,"File")+4,length($0)-index($0,"File")-3))
else
print
}
}' a
