awk system command 3

[superstarjpmc]

Hello there,

requriement:

I want to find the file type ( 'file <filename>' ) for all the files in the filesystem.

i used : system(&quot;file &quot;$1) inside a awk construct.

My question is how can I get the output of the system command in a variable

cheers
dj

cmd=&quot;file &quot; $1;

cmd | getline cmdOut; close(cmd);

# your output is in cmdOut variable

awk '
{

system(&quot;file &quot;$1)

} ' /tmp/host.out


This will produce a o/p like

/tmp/xx.awk: commands text

But I want to capture the o/p in a variable inside the awk program itself.

cmd=&quot;file &quot; $1;
while ( cmd | getline cmdOut ) {
print cmdOut # Proceed result line cmdOut
}
close(cmd);
}
