hi all,

im trying to run a command like this -

find -type f -exec fsfileinfo {} \; | grep Media

so what this will do is print out on the screen all the Media/tape numbers that contain a file but i get a long list as it prints the same numbers aswell not just unique numbers only

is there a way to just print tape numbers just once if there unique?

many thanks,

rob

You could pipe the line into sort specifying a unique sort on the specific field. You didn't show what your output looks like so I don't know which field would be the tape number (or if your tape number is actually just a number rather than alphanumeric).

Testing with "ls -l" output on my CentOS system:

Sort by permissions (first column) which is NOT numeric:
ls -l |sort -uk1.1,1.12

Sort by links (second column):
ls -l |sort -unk2

Usually sort by an entire field just requires the field number as in the second example above but it appears that sorts on alpha are requiring the full field specification including the trailing space.

-u = unique
-n = numeric sort
-k = field specification

Default field separator is white space.

If you're doing pure tape numbers counting which field has the tape number and doing the -unk<field> should work.

Indeed. Please show some lines of output that you wish filtered.

sorry guys been very busy at work,

i attach the screenshot of what the results are meant to look like using this command -

fsfileinfo file_name

but because im doing a fsfileinfo on the whole folder instead of just one file what you do is you cd out of the directory and do this command -

find -type f -exec fsfileinfo {} \; | grep Media

this finds all the media ie tape numbers for all the files in the folder but i get masses of screenshots, so i was just wondering can i just make a nice list of unique tapes i need instead of it listing all of them

Check out awk.

awk is a simple scripting language to scan and modify text. Its syntax is basically a lot of implied if-then statements.

If you are not in the directory hierarchy containing your target files, then change the path for find. If you need to restrict to certain file names, then add -name
