Shell Programming and Scripting

So, do you mean that green part can be ignored?
Its a part of time stamp afterall.please do confirm this.

Also, What about the second part ? you didn't answer that!

no..it cannot be ignored...

sorry for not answering your question...
ls -lrt 10.0.1.79*this is the output:
10.0.1.79_20100601.090108699
total 24
10.0.1.79_20100601.090149586
total 24
10.0.1.79_20100601.090022717
total 27804
10.0.1.79_20100601.085868276
total 30740

i don't think the latest one is the last.
i think it based on the total.

the directory name is based on :
host +"_"+ Time.now.strftime(%Y%m%d.%M%S")+sprintf("%.5d",rand(100000))

you are using random number for last five digits.

try this if it works:

Code:

ls -d 10.0.1.79* | sort -t"_" -nk2.1,2.4 -k2.5,2.6 -k2.7,2.8 -k2.10,2.11 -k2.12,2.13

this will try to sort the file based in the date/time present in the dir-name.
here the last five digit (random numbers) has been ignored.

still first try only below and check for the last dir name.

Code:

ls -lrtd 10.0.1.79*

thanks for detail info.

ls -d 10.0.1.79* | sort -t"_" -nk2.1,2.4 -k2.5,2.6 -k2.7,2.8 -k2.10,2.11 -k2.12,2.13
yup this is works.
it display the latest directory.

ls -lrtd 10.0.1.79*
the output are:
10.0.1.79_20100601.090108699
10.0.1.79_20100601.090149586
10.0.1.79_20100601.090022717
10.0.1.79_20100601.085868276

thanks
