Tilde Slash Bin - Commands That Make Life Easier

Some commands that I've made and kept in the ~/bin of every machine I use.

These bash utility scripts are not one-size-fits-all, so I would recommend symlinking the useful scripts from your repo directory to ~/bin instead of cloning into ~/bin.

I've used these scripts on OS X, Ubuntu, and CentOS.

count

A way to count how many characters you have. It takes every single character after count and outputs that length. Better than wc -l because it'll include whitespace.

Example

$ count I want to count how long this is
32

git-snapshot

Ever had a feature that's 75% done, but you can't figure out that one critical bug? You don't want to commit because the code's broken, but you would like to have a place to resume if you end up breaking more things in the bug hunting process.

Enter git-snapshot. It'll take -u or -p from git stash and give you a nicely formatted stash (either with your message or a default of Snapshot: <branchname> <datetime>), then immediately apply that stash so you can keep working.

Example

$ git snapshot
Saved working directory and index state On my-cool-branch: "Snapshot: my-cool-branch Tue Oct 29 14:18:23 MST 2013"
HEAD is now at d3412bc My commit message
# On branch my-cool-branch
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   my/cool/changes
#
no changes added to commit (use "git add" and/or "git commit -a")

mvln

Ever put something in a directory, then realized it needs to be somewhere else, but you still want to symlink to the current directory? mvln does this in one fluid step.

Example

$ mvln ~/git/my-awesome-command /usr/local/bin/my-awesome-command

$ ll ~/git/my-awesome-command
lrwxr-xr-x  1 username  root  3 Oct 29 16:18 /Users/username/git/my-awesome-command -> /usr/local/bin/my-awesome-command

pingg

Ping google.com. Keep trying to ping it as long as it's failing. Optionally, supply a parameter to specify how often ping should be pinging (the number is passed as the argument to the -i parameter).

Useful if you want to check connectivity to the Internet.

Example

$ pingg
PING google.com (74.125.239.5): 56 data bytes
64 bytes from 74.125.239.5: icmp_seq=0 ttl=58 time=5.394 ms
^C
--- google.com ping statistics ---
1 packets transmitted, 1 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 5.394/5.394/5.394/0.000 ms

rep

rep is like watch in that you can repeat commands every n seconds (watch defaults to 2 seconds, rep does not have a default). rep is better than watch in some cases because you can see the output of the older commands, while watch will only show you the output of the most recent command.

While this does work with functions, it fails with aliases due to how bash works. Convert aliases to functions if you need to use them with rep.

Example

$ # computer under heavy load due to compiling gcc, I want to monitor load over time
$ rep 1 uptime
 14:26:09 up 354 days, 14 min, 16 users,  load average: 5.40, 5.69, 7.51
 14:26:10 up 354 days, 14 min, 16 users,  load average: 5.45, 5.70, 7.48
...

git-supa-clean

git-supa-clean is when you want your working directory to be really, really clean. It removes staged, unstaged, and untracked changes to leave your code spotless.

Example

$ git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

        modified:   foo

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   bar

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        baz
$ git supa-clean
$ git status
On branch master
nothing to commit, working directory clean

git-supa-quickfix

git-supa-quickfix adds all changes, ammends the latest commit, and force pushes that commit. Sometimes you accidentally typo something and realize it just moments after. Just supa-quickfix it!

Example

tbd

git-blep

git-blep does a git blame on a git grep! How cool!

Example

tbd

git-stash-staged

Sometimes it's easier to git add some files or git add -p some particular changes than to git stash save -p those changes. If you already have some changes staged and you want to stash them instead of committing, this is the tool for you!

Example

tbd

goplayground

Makes a "hello world" go program in your editor. Upon exiting, goplayground will attempt to run the program.

Example

tbd
