Shell Programming and Scripting

Hello everyone

I am completely new to shell scripting in linux. I wan to write a script to search for a certain string from a .txt file and copy the string which apears just after tat searched string.

Eg: in a file- try.txt , we have a line saying: "roses are red, so what do i do"

I want ot search for the string "roses" and then copy the next string i.e. "are" and assign it to a variable.

Could anyone help me with this.

Like this since you are in Linux:

Code:

$ cat file
roses are red, so what do i do
nothing, just get the next string

Code:

$ var=$(grep -oP '(?<=roses )\S+' file)
$ echo $var
are

Guru.

Hey!!!

Welcome to the Unix and Linux Forum!!!!

Try someting like this,

First of all, you haven't mentioned, What shell you are using, Here you go with bash.

Code:

var=$(sed 's/.*roses \([^ ]*\).*/\1/g' try.txt)
echo $var

Please use code tag for code samples and data samples in future.

Thanks,

Cheers,
Ranga

Code:

$ cat temp.sh
var=`awk '{ for (i=1; i<NF; i++) { if ($i ~ /roses/) { i++; print $i; exit }}}' try.txt`
echo $var

Code:

$ ./temp.sh
