also lets you delete stuff.
# analyze current working dir, stay in the same filesystem

Bscp copies a single file or block device over an SSH connection, transferring only the parts that have changed.
In other words, it handles the edge case where rsync fails.
# The default BLOCKSIZE is 65536 (64 KiB).
# The default HASH algorithm is sha256 (SHA-256).
bscp SRC HOST:DEST [BLOCKSIZE] [HASH]

mc
Try using it over the network too, once you have it open:
cd sftp://user@host
or if that doesnt work
cd sh://user@host

This is the only tool we’ve found that actually lets us easily set all the things we need to to get programs to open the way we want.
these don’t really need introduction. here’s some recipes.
# recursive grep but better because it ignores dev nodes
find /path -print0 -type f | xargs -0 grep 'pattern'
# same thing but don't traverse mounts
find /path -print0 -xdev -type f | xargs -0 grep 'pattern'
# filter the contents of a single directory (better than `ls | grep`)
# -mindepth 1 prevents printing parent dir
# -maxdepth 1 prevents recursing deeper
find /path -mindepth 1 -maxdepth 1 [args...]
# Learn what changes to the filesystem a different process is making
# This detects files with modification dates newer than the checkpoint
touch /tmp/checkpoint
some_command_you_want_to_learn_about
find / -newer /tmp/checkpoint
# Same thing but for access time. Only works if you're using atime as a mount
# option, and not relatime or noatime.
touch /tmp/checkpoint
some_command_you_want_to_learn_about
find / -neweraa /tmp/checkpoint
# change the passphrase on a private key (or remove it)
ssh-keygen -p -f path/to/key
This is in sys-apps/sg3_utils.
Apparently this can lock up some USB drives. be careful. Works on my WD Passport.

swiss army knife of playing media. if you install yt-dlp too it can even play
youtube videos directly!
good tutorial in
man 7 cmus-tutorial
works well even with networked filesystems!
Basically, use a jq query, but run yq or tomlq instead of jq. It’ll parse
the input, convert it to json, then feed it to jq. By default it will output
whatever jq returns as-is, but you can ask it to convret it back to the
original format too.

apt, apt-get, aptitude are all frontends to the debian package database. Here’s some commands for dealing in them.
# Install a package from backports
apt install -t <release>-backports somepackage
# If you decide using backports was a mistake actually, List all packages
# installed from backports. Note dependencies are marked with "A" for automatic
aptitude search '?narrow(~i, ~Abackports)'
https://github.com/thesamesam/sam-gentoo-scripts/blob/main/maint/bump-go
# run this on the thingy that builds binary packages to
# rebuild the metadata index
emaint binhost --fix
# delete source for anything without an ebuild in any repos
eclean-dist
# delete source for anything that isn't installed
eclean-dist -d
# delete binary packages from /usr/portage/packages for anything
# without an ebuild
eclean-pkg
# delete binary packages from /usr/portage/packages for anything
# that isn't installed
eclean-pkg -d
### clear out old kernels
eclean-kernel
# verify integrity of files of all installed packages
equery check -o '*/*'
# list installed packages with no maintainer
qlist -I \
| xargs equery -CN m -m 2>/dev/null \
| sed -n '/^ \*/h; /None specified/{ x; p }'
# list all installed packages
qlist -I
in general, it’s a good program for dealing with merges/rebases. we use it regularly. Free version only has light mode :/.
git -c rebase.instructionFormat='%s%nexec GIT_COMMITTER_DATE="%cD" GIT_AUTHOR_DATE="%aD" git commit --amend --no-edit --reset-author' rebase -f <commit/branch before wrong author and email, or --root to rebase all>
for when i forget to signoff my stuff when doing gentoo package maintenance.
git rebase --exec 'git commit --amend --no-edit -n -S -s' origin/dev

This is an easier to use alternative to diff for the purposes of side-by-side
diffing. It’s not interested in replacing diff for automation purposes.
icdiff -r /path/to/dir1 /path/to/dir2

Not our script, but we modified it slightly to make it work with modern irssi. Put it in ~/.irssi/scripts/autorun/. Read the script for how to set up keybinds
