execution delay for listing files.

[pinga123]

Hi ,

Whenever i try to execute ls with l as an option the system displays the output with significant delay.
However only ls works fine.

this happens only when i m in /usr/local/sbin where all my executable resides.

The workload on server is not more than 1.

What could be the reason .

# which ls
alias ls='ls --color=tty'
        /bin/ls

Distribution details.

# lsb_release -a
LSB Version:    :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch
Distributor ID: EnterpriseEnterpriseServer
Description:    Enterprise Linux Enterprise Linux Server release 5.2 (Carthage)
Release:        5.2
Codename:       Carthage

Here is the difference .

#time ls
real    0m0.004s
user    0m0.000s
sys     0m0.002s
#time ls -ltr
real    3m2.443s
user    0m0.003s
sys     0m0.002s

As you surmise, the aliased "ls" command may be at fault. Try running the command "/bin/ls -ltr" and see how that works.

Well the t flag sorts by modification time and then the r flag reverses the order, so maybe if there are a lot of files in that directory the sort is taking time, try running the following to identify which flag is slowing it down

time ls
time ls -l
time ls -t
time ls -r

It was a problem of ownership .When i tried executing ls -n it resulted in faster responce .
-n option make sure that only uid and gid are displayed.

So i figured out that one of the folder has wrong ownership.
I changed the ownership of the folder and the problem is solved.
