Date capture & filter

Shell Programming and Scripting
1

Dear All,

I am capturing system date and creating the file by using that time stamp, file is getting appended with checks of application & database check logs.

But when the date is in between 1 to 9 both inclusive, it appends a single space to file name but after 9th it works fine.

tmstmp=`date +%e%b%Y_%H%M%S`
file_name=Daily_Check"_"${tmstmp}.out

Output for the same is below:
Daily_Check_ 7Jan2013_124706.out
Daily_Check_26Jan2013_070036.out

Desired output is below:
Daily_Check_7Jan2013_124706.out
Daily_Check_26Jan2013_070036.out

Request you to help for the same.

tmstmp=`date +%e%b%Y_%H%M%S`
tmstmp=${tmstmp# }
file_name=Daily_Check"_"${tmstmp}.out

Use %d instead of %e to get the day zero-padded, or use %-e to rule out padding (may be misleading:

$ date +%-e%-m%Y -dtomorrow
122013

).

Thanks your code works absolutely fine, can you explain what had happened here and how it had removed the blank space from the in between....

Refer string manipulation (link removed)

Thanks RudiC, I had used

%d

and it's giving the output by padding zero to it and it's keeping the lenght of the file name constant.

I tried to use

%-e

but it's not giving the desired output.
