i want to get the latest file from the directory ...
then extract the specific lines from it(the latest file which i extracted) starting from the charcters ...INSTANCEID ...Program started at.... program ended at ....
i want to do it for the multiple dirctories at the same time
could anyone give me the script for this
You really did not provide much detail - examples of input and desired output. However, the following should get you started. See what you can write of a script, and post back follow-up questions.
Either of the following will give you the latest (most recent file). There are many ways to find this out, by the way.
> ls -lt | grep "^-" | head -1 | awk {'print $9'}
comp.log
> ls -lt | grep "^-" | head -1 | tr -s " " | cut -d" " -f9
comp.log
you can set a variable for the results, with
file1=$(ls -lt | grep "^-" | head -1 | awk {'print $9'})
A script can then cat or head or grep on $file1
I would suggest trying to do this for one file. Once you can do that, it is farily easy to insert the command(s) into a loop function.
Hello there
thanu for ur reply.....but i m not getting the desired output
ill explain u in detail.....wht we do
we first use the command ls -lt /apps/psoft............../FNTEDP01*
through which we get the no of files in the directory of the format
/apps..................../FNTEDP01_1423165.LOG
from this we pick the latest file as per the date
and then use more command to get the information and then the tail command if we dont get the entire information from the more
(we dont use the cat command bec some of the files may be very large )
then pick the information from the file
we do this for several files ....
Hi ,
Kindly check whether the below script is working or not.
file = `ls -lt | grep "^-" | head -1 | awk { print $9 }`
cat file | grep "^FNTEDP01" > file1
for i in `cat file1`
do
more $i
done
Thanks and Regards,
