Backup of Files With Given Extension

Filed under: Uncategorized — hdahlol @ 8:15 pm

I often need to make backup of a certain class of files, say all text files in a folder. A nice bash one-liner to achieve that is:

for i in *.txt; do cp “$i” “$i.backup”; done

On Windows this is even simpler. There you can simply do:

copy *.txt *.txt.backup
