Commands

command-cheatsheet

Find and tar up a bunch of shit matching a name (good for copying Mac config files to a new system)
find ./ -iname '*bettersnaptool*' | tar cpvf snappage.tar -T -

Recursively find and delete a bunch of shit:
find ./ -iname '*appstore*' | xargs rm -rfv

"Uninstall" a tarball you just installed, provided that you run that command from the same directory as you ran the unpack command, and that you didn’t overwrite any existing files at unpack:
tar -tf filename.tar | xargs rm -rfv

Grab a bunch of links from a web page:
lynx -dump -hiddenlinks=listonly https://www.computerhistory.org/collections/catalog/102661095 | grep pdf | awk '{print $2}' > pdfs

Scriptily uninstall a bunch of stuff from an Android device:
Building up on banshee's one liner, for me there was a trailing \r, removing it was needed, as such:

adb shell 'pm list packages -f' | sed -e 's/.*=//' | sed 's/\r//g' | sort

Only then I was able to do get the following to work:

adb shell 'pm list packages -f' | sed -e 's/.*=//' | sed 's/\r//g' | grep "com.foobar" | while read pkg; do adb uninstall $pkg; done;
