Quickly Updating Files using SED
I had a client send several PDFs (around 100) and I wanted to quickly update the names of all of the files using a similar pattern. For example, I wanted to switch all files from something like this: "1812 Governors Race.pdf", to "1812_Governor.pdf"
All files had different years, so I needed to preserve the year.
The following bash script took care of it:
for old in *.pdf do new=$(echo $old | sed -e 's/ Governors Race/_Governor/') mv -v "$old" "$new" done
Note that this doesn't work recursively. It's a rather quick and dirty solution. This will only work for the files in the same directory.
