Use codetag

Try

Code:
$ awk -F'[_]' 'NR==1 || p!~$1{close(f);f="Out"++i".txt"}{print $0>f;p=$1}' file

Code:
$ ls Out* -1 
Out1.txt
Out2.txt

Could you please explain the functionality of the above code..

My requirement is to search for a string in each line and print that line if it starts with ABC_XY_*
And those are not start with ABC_XY_* they will be written into another file.

My source file which I am reading is file1.txt

Thanks for your quick response.

Hi there, very elegant solution just tried it on my Android tablet and it worked apart from the output file names which came out as 1.text and 2.text ? Any idea why ?

create a script test.sh =

cat test.sh contains below commands -
Code:
awk '($1 ~ /ABC_XY_/){print $0}' file1.txt > out1.txt
awk '($1 !~ /ABC_XY_/){print $0}' file2.txt > out2.txt

Both input files should be file1.text :-)
