Script help please

[Paula J Frazer-Campbell]

Help from script experts please.

Dir listing gives these file names

uv8980926993aa
uv8981027062aa
us9105010894aa
us9047009985aa

I require to pull out the 3 to 7th chars,

I.e.
uv8980926993aa
to become
89809

I have got this far :-

ll | awk '{print $9}' | sed "s/^uv//" | sed "s/^us//" | sed "s/aa//"

To give this:-

8980926993
8981027062
9105010894
9047009985

But what next ??


Thanks in advance

Paula

Hi,

What is about :

ll | awk '{print $9}' | cut -c3-7

Try using 'cut':

$ ls | cut -c 3-7

or

ll | awk '{print $9}' | sed "s/uv\([0-9]\{5\}\)\(.*$\)/\1/"

Hi

This to check.script with dir as parameter

file=$1
for f in $(ls -1 $file|sed -e 's:^.*/::g')
do
echo $f"|"$(echo $f|cut -c3-7)
done

This to do your option.

file=$1
for f in $(ls -1 $file|sed -e 's:^.*/::g')
do
echo $(echo $f|cut -c3-7)
done

Hi Paula:

Just for grins-and-giggles (although Harry's first solution using the 'substr' function of 'awk' my choice too):

# ls -l|tr -s " " "\t"|cut -f9|cut -c3-7

Regards!

Hi Paula,

More confusion...

If use ll, "grep -v ^total" needs to be added. I'd use ls instead of ll. You can explicitly say "ls -1" for one column output but ls will do that by default when it's output is piped to another command.

My vote for speed and simplicity is Steven Gillard's:
ls | cut -c 3-7

Paula,

Playing with the uv spool files I see! Keep in mind that sometimes files in the directory no longer will be in the uv index file and therefore will not be accessible as hold entries from the uv commandline. OTOH, this also means that you can safely wack them, as far as uv is concerned.

Yes wonderful universe - I am writing an old file cleanup routine and intend to fire my results at:-

usm -k

As as you know Unix file name and Universe file name when using the usm are different.

Instead of just doing an rm on them I thought it safer to let the universe command deal with them.

Et Al.

All answer were worth 10 points - there is certainly more than one way to skin a cat.


:^)

Thanks

Paula,

Yes, been there, done that. Some caveats: you have to run this as root, but you can do it in cron. You also have to allow for the usm command to fail because the entry in the uv index is gone, so it won't remove the file. You can get around that like this:

usm -k || rm -f [file]

also be aware that not all of the usm/usa command options work, or work as advertised.
