how to print the certain lines in a file to different files
Hi All,

File that I have:
Code:
 
<ct>
<name>group
<value>1
<value>2
<value>3
</ct>-->file

The output that I needed is
Code:
 
<ct>
<name>group
<value>1 -->file1
 
<ct>
<name>group
<value>2 -->file2
 
<ct>
<name>group
<value>3 -->file3

I have tried to use this code
Code:
 
awk '/^<ct>/{cnt=3}cnt-->0'

but just can give me the output for file1.
Is there any other method?
Thanks for help!

Code:
cat abc.txt | perl -e 'while (<>){
chomp;
if(m/^\<value\>(.*)$/){
open my $fh , ">" , "file$1"  || die "$!";
print $fh  "$comm_lines"."$_";
close $fh;
next;
}
$comm_lines .= $_."\n";
}'

Try...
Code:
awk -F \> '/<ct>/{c=$0}/<name>/{n=$0}/<value>/{printf("%s\n%s\n%s\n",c,n,$0)>"file" $2}' file

Result...
Code:
$ head file*
==> file <==
<ct>
<name>group
<value>1
<value>2
<value>3
</ct>

==> file1 <==
<ct>
<name>group
<value>1

==> file2 <==
<ct>
<name>group
<value>2

==> file3 <==
<ct>
<name>group
<value>3

Hi Ygor,

Can you please explain the code?

May I know why need to have "$3" when redirect the file?

Besides I have tried the code, but in each file I just have the output of <wt> tag

I just modify abit


Code:
awk  ' BEGIN {FS="[<>]"} 
/<ct>/{c=$0}/<name>/{n=$0}/<value>/{printf("%s\n%s\n%s\n</ct>\n",c,n,$0)>"file" $3}/<wt>/{print $0>"file" ++c}' file

The output that I get:

0
<wt>a</wt>

1
<wt>b</wt>

2
<wt>c</wt>

3
<ct>
<name>group</name>
<value>1</value>
<ct>
<name>group</name>
<value>2</value>
<ct>
<name>group</name>
<value>13</value>

Thanks,
