Top Forums Shell Programming and Scripting Check how many minutes ago the last file created Post 302896820 by blakeoft on Wednesday 9th of April 2014 11:14:58 AM

I think I have a fix for my code above. Try this:
Code:
FOLDER="/nas/testfolder"
FILE=$(ls -alt ${FOLDER} | awk '$NF ~ /^Test/ {print $NF}' | head -1)
FILE_TIME=$(date --reference=$FOLDER/$FILE +%s)
NOW_TIME=$(date +%s) ; echo $((($NOW_TIME-$FILE_TIME)/60))

FOLDER is the folder that you want to look in.

FILE is the most recent file matching your pattern: Long list all files in FOLDER and sort by time. Pipe to awk. Print the last field with files that match the pattern "^Test". Pipe to head. Print the first entry.

FILE_TIME is the number of seconds past a universal date that I don't recall.

NOW_TIME is the number of seconds past that date until now.

Then print the difference of the two times divided by 60.

Note that my code might not work properly if no file matches the pattern.
