.inputrc keybinding to wrap current line in inotifytools for instant compile/test-as-you-save-loop
Assuming you've written all of make -j hfst-tokenize && echo doavtter gr?dakursa|./hfst-tokenize --gtd tokeniser-gramcheck-gt-desc.pmhfst and want that to execute every time you :w in vim (or C-xC-s in Emacs), just hit and it'll turn into $ while true; do ( make -j hfst-tokenize && e doavtter gr?dakursa|./hfst-tokenize --gtd tokeniser-gramcheck-gt-desc.pmhfst ); inotifywait -q -e modify -e close_write *; done with the cursor right before the ')'. Hit enter, and it'll run on each save. Requires the package inotify-tools installed.

sort the contents of a text file in place.
sorts the contents of a file without the need for a second file to take the sorted output. This was previously entered as `sort -g list.txt -o $_` but as others have pointed out the $_ references the previous command. so this would've worked had that been the second part of a command joined with && like: cat list.txt && sort -g list.txt -o $_ The user below me Robin had the most correct command.

Merge various PDF files

replace spaces in filenames with underscores
This command will replace all the spaces in all the filenames of the current directory with underscores. There are other commands that do this here, but this one is the easiest and shortest.

Give any files that don't already have it group read permission under the current folder (recursive)
Makes any files in the current directory (and any sub-directories) group-readable. Using the "! -perm /g=r" limits the number of files to only those that do not already have this property Using "+" on the end of the -exec body tells find to build the entire command by appending all matching files before execution, so invokes chmod once only, not once per file.
