SSHFS Mount Script

Following are a pair of scripts to mount and unmount files systems via SFTP using Fuse, they are used on Crin3.

# the place file systems are to be mounted
MOUNT_POINT="/media"
if [[ ! -d "$MOUNT_POINT" ]]; then

# check for server to mount on standard input 
if [[ $1 ]]; then
  SERVER=$1
elif [[ ! $1 ]]; then
  echo "Type the server you want to mount and then [ENTER]:"
  read server
  SERVER=$server
fi

  echo "to add entries like this for each server:"
  echo
  echo "Host example"
  echo "   User root"
  echo "   Hostname example.org"
  echo
  exit 1

if [[ ! -d "$MOUNT_POINT/$SERVER" ]]; then
  echo "Creating $MOUNT_POINT/$SERVER"

# check is the file system appears to already be mounted

if [[ $DF ]]; then
  echo "It appears that $SERVER is already mounted at $DF?"
  exit 1

sshfs $SERVER:/ $MOUNT_POINT/$SERVER/ && \
  # if this succeeded
  { echo "Mounted $SERVER:/ on $MOUNT_POINT/$SERVER/" ; exit 0 ; } || \
