empty/blank lines
lines beginning with #
lines beginning with //
lines beginning with /*
lines beginning with a space and then *
lines beginning with */
It also deletes the lines if there's whitespace before any of the above.
Add an alias to use in .bashrc like this:
alias stripcomments="sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d'"

Like the http://www.commandlinefu.com/commands/view/6327/open-file-with-sudo-when-there-is-no-write-permission, but works (in zsh; my commandlinefu is not strong enough to understand why bash don't like it) with vim options, like -O, and many input files. There could be other mistakes.
Usage: jd dir
Requires globstar. To set globstar use:
shopt -s globstar

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 '|'! Jk. 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 ras_a.h ras_a.cpp ras_b.h ras_b.cpp to: 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.
Could use your ssh bash history if your known_hosts are hashed and you want to keep it hashed
-d, --delete Delete a user?s password (make it empty). This is a quick way to disable a password for an account. It will set the named account passwordless.
