Bug getting filesize

Hello,

I have a script that should store file size in a variable $filesize.
I don't know what is the best way to do it.

I tried
ls -lt myfile.txt | sed something >$filesize

but I don't know how to use sed to get filesize. I know that the owner of the file is root and then we have some spaces, then the file size value then some spaces.

Maybe there is also other way to do it

Smilie

Code:
filesize=`ls -l myfile.txt | awk '{ print $5 }'`

thanks

ls is in a ssh command

Code:
$filesize = `ssh root@$myip (ls -lt myfile.txt | awk '{ print $5 }')`

to know filesize on a remote computer

will it work knowing that I got public key authorized for $myip computer.

If you have stat (man 1 stat) installed this is a more concise way to get your filesize.

Assigning a shell variable in such a way will surely not work... Are you using Perl?

For sh/bash this will work:
Code:
filesize=`ssh root@$myip ls -l myfile.txt | awk '{ print $5 }'`

Nop, I don't have perl

I have an error not a valid identifier but I have the good result in it.

set $bibi=`ls -lk myfile | awk '{print $5}'`

bash : error `21 not a valid identifier,
21 is the size of the file

if you want to assign the result to bibi, then
Code:
bibi=`ls -l .... .`
