UNIX for Dummies Questions & Answers

I found an weird thing when i browse through my files with ls -sh option.

Code:

512M -rw-rw---- 1  user user   20K  Jul  3 23:00 2012 /path/a.MYI .....(1)
512M -rw-rw---- 1  user user   19K  Jul  3 23:00 2012 /path/b.MYI .....(2)
512M -rw-rw---- 1  user user   16K  Jul  3 23:00 2012 /path/c.MYI .....(3)
512M -rw-rw---- 1  user user  5.0K  Jul  9 15:30 2012 /path/d.MYI .....(4)
4.0K -rw-rw---- 1  user user  4.0K  Jul  3 23:00 2012 /path/e.MYI .....(5)

The size returned by -s option and -l option are different (1)~(4)
I understand that -s prints the allocated size in blocks, but i expect smaller figure in this case.
But the result shows 512M block size for a file of 20K.
Hmm.. can i assume that something is wrong?
Or anyone can explain this situation?
Thank you.

What OS do you have?

Please post the output of

Code:

df -k
cat /etc/mnttab

And no, you cannot assume something is wrong. It probably has to do with how the filesystem was set up. And what type of filesystem you have: ufs, ext3, etc.

Depending on your OS this file could alternatively be named /etc/filesystems (AIX) or /etc/fstab (Linux, FreeBSD?) or even something different.

Either way, Jim wants to know what is mounted where and probably which (types of) filesystems are being used.

I hope this helps.

What Operating System and version are you running and what Shell you you use?
The order of the fields from your ls command is weird. I wonder if someone has modied your ls command.
Please post the output from:

Code:

alias | grep "ls"
type ls

Post #1 does not match the commands to the output and appears to show 5 different files. Please re-post showing clearly what command you actually typed to get each line of output, making it clear where you believe there is an anomaly.
