help pulling data string using Awk

I'm working on a script to locate newly changed files and send out an email, I need help pulling just the file name from the resulting find command.

my find command is-
find /mnt/ABC_POOL/ABC_BUILD/ -type f -name .zip -prune -o -mmin -5 -type f -print
the result from the above would be something like this

/mnt/ABC_POOL/ABC_BUILD/XSTORE/ELC/ABC_xyz_7.1.4.17_1.12.3-installx.zip
I would like to use just the zip file name as my final result by using awk or sed to remove the path and leave just the file name, keeping in mind that the full path is not always the same.
I'm hoping there is a way to remove everything from start of string leaving the last part after the last / that would be the file name.

Any idea what would be the best way, I attempted awk -F"\t" but did not work.

You could try "basename", a utility exactly meant for that purpose:

find /mnt/ABC_POOL/ABC_BUILD/ -type f -name .zip -prune -o -mmin -5 -type f -print | while read file
  do
    echo $(basename $file)
  done

Open in new window

If the result of the find command is always just one filename you could put it like this:

FILE=$(basename $(find /mnt/ABC_POOL/ABC_BUILD/ -type f -name .zip -prune -o -mmin -5 -type f -print))

You can of course use "awk", because "awk" can do just everything:

find /mnt/ABC_POOL/ABC_BUILD/ -type f -name .zip -prune -o -mmin -5 -type f -print | awk '{F=split($0,A,"/"); print A[F]}'

I have completed my script, thanks to you woolmilkporc, I have one issue I just noticed, the output is listing all files in sequence with a space separating each file, is there a way to have the output of the command I'm using to list it all like ls -l would in a column?
here is my command as a variable, I use the output of the variable to email the list of files.

FILE=$(basename $(find /mnt/ABC_POOL/ABC_BUILD/ -type f -newerct '5 minute ago' -print))

How do you use the variable?

If it's something like

echo $FILE | mailx ... ...

you can try

echo $FILE | tr " " "\n" | mailx... ...

If you're using a different approach please let me know .

yes I'm using echo $FILE in to a temp file to be used for the body of the email like.

echo $FILE > /mnt/ABC_POOL/ABC_BUILD/newfile

so the below should work?

echo $FILE | tr " " "\n" > /mnt/ABC_POOL/ABC_BUILD/newfile

woolmilkporc

Yes, but if you want the output to go to a file you can simply do this:

find /mnt/ABC_POOL/ABC_BUILD/ -type f -newerct '5 minute ago' -print | xargs -n1 basename > /mnt/ABC_POOL/ABC_BUILD/newfile

Ok, i'm using the variable to validate if a file is found in an if statement, the validation I'm using is
if [ -s $FILE ] and has been working so far.
Thanks for your help, trying to better my limited bash scripting capabilities.
