Shell Programming and Scripting

Hi all,

I have a question. I have a folder. I want to find the list of files that are modified today and store all those file names in a variable as comma separated values. I thought of using
"find . -mtime 0" command to find the list of files modified today. Also to get those values of file name stored in a variable, I thought of using
"find . -mtime 0 | awk '{print $1}'" command. But 1 value is hard coded in that. I need to know how many outputs coming out of "find . -mtime 0" command so that i can dynamically vary my print statement in awk.

Any help on this.

Thanks in advance.

Thanks,

Which shell you are using (exact version if possible)?

You could try

Code:

var=$(find . mtime -1d | tr '\n' ',')

or

Code:

var=$(find . mtime -1d |perl -pi -e 's/\n/,/g')

Only issue with those is it will put a , on the end of the string.

Perhaps you could then just replace the end , with sed or something

Thanks for ur reply...

But when i execute both the exp, i m getting "find: invalid predicate `-1d'" error.... what would be the reason?

Depends on your shell and find version.

I was just doing that on solaris in sh.

try your original -mtime 0

Thank u very much... It s like a magic...

I tried with the following command

var=$(find . -mtime 0 | tr '\n' ',')

It gives me the result ".,./WS2003-WindowsMedia-BD.doc,./avcodec_sample.cpp," as these are the two files modified today in the server path.

Can u explain me how this command works?

Also what is the reason for "." coming as first name then followed by the file names?

If you don't want the trailing ,:

Code:

files="$(find . -mtime -1|paste -sd, -)"
