Shell script to set up a symlink to tmp for google chrome's cache.

chrome-symlink.sh

#!/bin/bash

# This shell script sets up a symlink to tmp for google chrome's
# cache, if one doesnt already exist. Useful due to the size of
# chrome's cache.

# One downside is that you will end up with a different cache
# on each computer you use - but this isn't a massive problem tbh.

ACTUAL=/tmp/$USER/cache/google-chrome
SYMLINK=~/.cache/google-chrome

mkdir -p $ACTUAL
chmod 700 /tmp/$USER

if [ $? -ne 0 ]; then
        echo "Unable to restrict access to folder /tmp/$USER"
        echo "The most probable cause is that someone else has already created this folder before you."
        echo "Try changing the ACTUAL variable in the shell script."
        exit 1
fi

if [ -e $SYMLINK ]; then
  # Directory exists - is it a symlink?
  if [ -L $SYMLINK ]; then
    # We're done!
    exit 0
  else
    # Try and delete it.
    rm -rf $SYMLINK
    if [ $? -ne 0 ]; then
      # Bugger.
      echo "Unable to delete chrome cache folder."
      echo "Shut down any running instance of chrome and try running the script again."
      exit 1
    fi
  fi
fi

# Okay, need to create symlink.
ln -s $ACTUAL $SYMLINK

Good point Chris, I'll get that fixed.

Update: Fixed.
