I don't know if you've used sqsh before. But it has a handy feature that allows you to switch into vim to complete editing of whatever complicated SQL statement you are trying to run.

But I got to thinking -- why doesn't bash have that? Well, it does. It's called '|'!


Seriously, I'm pretty sure this flow of commands will revolutionize how I administer files. And b/c everything is a file on *nx based distros, well, it's handy.

First, if your ls is aliased to ls --color=auto, then create another alias in your .bashrc:

alias lsp='ls --color=none'

Now, let's say you want to rename all files that begin with the prefix 'ras' to files that begin with a 'raster' prefix.

You could do it with some bash substitution. But who remembers that? I remember vim macros because I can remember to press 'qa' and how to move around in vim. Plus, it's more incremental. You can check things along the way. That is the secret to development and probably the universe. So type something like:

lsp | grep ras

Are those all the files you need to move? If not, modify and re-grep. If so, pipe it to vim.

lsp | grep ras | vim -

Now run your vim macros to modify the first line. Assuming you use 'w' and 'b' to move around, etc., it should work for all lines. Hold down '@@', etc., until your list of files has been modified from






mv ras_a.h raster_a.h

mv ras_a.cpp raster_a.cpp

mv ras_b.h raster_b.h

mv ras_b.h raster_b.cpp

then run :%!bash

then run :q!

then be like, whaaaaa? as you realize your workflow got a little more continuous. maybe. YMMV.

Also works with files:

cat file

Hello world

For those files in current folder that would be shown in `ls *ext`, for some extension ext, move/rename that file removing the .ext suffix from the file name.

It uses Bash's parameter substitution, as seen in
