Will's bin directory

wharris_bin

A collection of little scripts that I keep in my ~/bin directory. I use them on my Mac, and some are specific to OS X, but some may work on other platforms.

Contents

• athome - detect when the host is on the home network.

  The athome utility uses the current SSID to guess whether it's running on a machine that is connected to your home network. The home network is defined by the HOME_SSID environment variable. If HOME_SSID is set and athome is running on a Mac connected to a wireless network with an SSID that matches HOME_SSID then athome returns true. athome returns false if is run a Mac that is not connected to a wireless network with an SSID that matches HOME_SSID. athome returns false if HOME_SSID is not set.

• backup.sh - backup my home directory.

  This is run every night by cron. It just copies my home directory to a backup server.

  You'll need to set a couple of environment variables to use this tool:

  • BACKUP_PATH - The scp-style path to the backup destination. For example: backup.example.com:/Volumes/External\ HD/backup/mymachine/username/.
  • BACKUP_LOG - Local path the tool can log to. For example: /Users/username/log/backup.log.

• beep - make the terminal beep.

  Echoes an ASCII BEL character to STDOUT. This can be useful when waiting for a long-running command to finish. For example:

    find / -name "*.mp3" > ~/tmp/mp3s.txt 2> /dev/null ; beep
  

• cscript - run a C program like a script.

  cscript lets you write scripts in C, letting you compile and run single-line C programs with a one command. Just add a line like the following to the start of the source file and chmod it to be executable:

    #!/bin/sh cscript
  

  If you need a full example, see the beep script above.

• datestamp - output the date.

  Prints a newline followed by a #, a space, and the date.

• git-remote-new - create remote Git repository.

  Automates the task of creating a remote Git repository. Run git-remote-new new-repo-name from a local Git repository and you'll have a remote branch pointing to a new repository on your Git server called new-repo-name.git.

  You'll need to set up a couple of environment variables to use this tool:

  • REPO_SERVER - the SSH address of your Git server in the form [e-mail].

  • REPO_SERVER_GIT_PATH - the path on the server under which your repositories will be created. For example /home/username/git.

  The remote name defaults to origin, but you can override that by setting the environment variable REMOTE_NAME.

• git-remote-list - list remote Git repositorys.

  Lists repositories created with git-remote-new.

  You'll need to set up a couple of environment variables to use this tool:

  • REPO_SERVER - the SSH address of your Git server in the form [e-mail].

  • REPO_SERVER_GIT_PATH - the path on the server under which your repositories will be created. For example /home/username/git.

• growlexec - growl the success or failure of a command.

  Runs the command given in the arguments then sends a Growl notification of the success or failure of the command based on the command's return value.

• killjobs - kill background jobs.

  Kills all the background jobs for the current shell. This will not work from a sub-shell, so you'll need to execute it with something like the following:

    . ~/bin/killjobs
  

• orgname - set organization name in Xcode.

  Sets the default organization name that Xcode uses in the the copyright line for new files, so you don't have to keep replacing __MyCompanyName__. Example:

    orgname "My Company Ltd"
  

• pygrep - search for strings in a Python source tree.

  Run with pygrep search-term. This script greps through all the files below the current directory that look like Python source code.

• rbgrep - search for strings in a Ruby source tree.

  Run with rbgrep search-term. This script greps through all the files below the current directory that look like ruby code.

• restartvpn - restart a CiscoVPN client.

  Sometimes the Cisco's VPN client software stops working due to evil spirits. This script is a magical incantation that sometimes makes the client work again.

• srcgrep - search a source tree.

  Run with srcgrep search-term. This script greps through all the files below the current directory that look like source code.

• wdiff - frontend to opendiff.

  Use this as a --diff-cmd argument to svn diff in order to view your diffs using FileMerge.
