Get File Size In Bash Script Using DU and SED
 
Another option:

Code:
X=~/The_File
size=$(du -b ${X} | sed 's/\([0-9]*\)\(.*\)/\1/')

another way to skin the cat


ls -l $FILENAME | cut -d " " -f 6

'ls' is NOT reliable for telling file sizes. Use 'stat' it is most reliable.

tomines 12-17-2007 04:35 PM
Can you please explain why these other methods are not reliable?

gnashley 12-18-2007 03:25 AM
Not all programs determine the file size in the same way. Some methods simply don't give an accurate result.

I'll agree with H_TeXMeX_H. Using stat is the best method:
Code:
stat --printf="%s" file.any

Ooh! Yes, using stat is much better than what I came up with. Thank you!

Do "man stat".
