count bytes with awk

HI THERE!Do you know how can i count bytes if a file with awk?

I don't know about awk baut you could use "wc".

Yep, wc is the tool you want for that. It's handy for counting things. (stands for word count)

By default the output is number of lines, words, and bytes.

I must use the awk file....I have thought this...we know that every character is one byte, So the only thing that i must do is to count the characters. DO u agree?

Why must you use awk? Don't you have wc?

I find this aproach rather awkward :}
wc is the way to go ;)

Read the awk man page, if it can be done it's in there. Normally I would be happy to help out, but without a real reason to use the wrong tool, I can't seem to find the time. ;) wc is perfect, but even Perl is a better tool to use than awk, for this.

Awk program:

BEGIN {
system( "wc -c t1.awk") | getline theCount ;
}

END {
print theCount;
}

(Okay, I cheated and used "wc" from inside awk... sue me... ::grin:

hi alaios:

if you needto count bytes of one file:

bash> wc -c filename | awk '(print "total bytes in file: " $1}'

if you need to count bytes used by multiple files:

bash> ls -l | awk '{x=x+$5}; END {print "total bytes in directory: " x}'

good luck and happy coding ;>
