+**C**ount **L**ines **o**f **C**ode is an application included in the standard Ubuntu repositories that counts the lines of code separated by programming language.
+
+It is able to separate out blank lines, comment lines, and actual code lines in the count.  It's quick and easy to use for giving a quick statistic on any given code repository.
+
+To count lines of code in the current directory,
+
+```bash
+cloc .
+```
+
+An example from my website repository:
+
+```
+1019 text files.
+894 unique files.                                          
+158 files ignored.

+This post is part of a new series I'm starting where I quickly outline small Python snippets.
+
+If you have an application that you want to gracefully exit when the user presses CTRL-C here's the short snippet
+```python
+import signal
+import sys
+
+# Function that gets called when interrupt is found
+def signal_handler(sig, frame):
+  print('You pressed Ctrl+C!')
+  sys.exit(0)
+
+# Attach the function to the interrupt signal
+signal.signal(signal.SIGINT,signal_handler)
+
+print('Press Ctrl+C')
+```

+
+In case I forget again, by default when snaps are installed it doesn't populate in the `zsh` shell. To enable this add the following to `/etc/zsh/zprofile`
+
+```bash
+emulate sh -c 'source /etc/profile.d/apps-bin-path.sh'
+```
+
+In case you don't have `apps-bin-path.sh` in `/etc/profile.d/`, then here's the file as of this date:
+
+```bash
+# shellcheck shell=sh
+
+# Expand $PATH to include the directory where snappy applications go.
+snap_bin_path="/snap/bin"
+if [ -n "${PATH##*${snap_bin_path}}" -a -n "${PATH##*${snap_bin_path}:*}" ]; then
+    export PATH=$PATH:${snap_bin_path}
+fi
+
+# Ensure base distro defaults xdg path are set if nothing filed up some
+# defaults yet.
+if [ -z "$XDG_DATA_DIRS" ]; then
+    export XDG_DATA_DIRS="/usr/local/share:/usr/share"
+fi
+
+# Desktop files (used by desktop environments within both X11 and Wayland) are
+# looked for in XDG_DATA_DIRS; make sure it includes the relevant directory for
+# snappy applications' desktop files.
+snap_xdg_path="/var/lib/snapd/desktop"
+if [ -n "${XDG_DATA_DIRS##*${snap_xdg_path}}" -a -n "${XDG_DATA_DIRS##*${snap_xdg_path}:*}" ]; then
+    export XDG_DATA_DIRS="${XDG_DATA_DIRS}:${snap_xdg_path}"
+fi
+```
