#/usr/bin/tcsh
# clock.tcsh

# the script is executed inside a while without conditions
while 1
# time and date are formatted to show HH:MM:SS YYYY-MM-DD
set cmd = `date +"%H:%M:%S %F"`

# cursor's current position is saved through an escape sequence
echo -n "\033[s"

# Uncomment the next two lines to clean up the whole first line, although it causes a lot of blinking
#tput cup 0 0 # positions on row 0 col 0 (left top corner)
#tput el # cleans from position to end of line

# to place the clock on the appropriate column, subtract the length of 'HH:MM:SS YYYY-MM-DD', which is 19,
# from the total number of columns
set cols = `tput cols`
@ C = ( $cols - 19 )
tput cup 0 $C # positions cursor at row 0 col $C

# clock will be shown green inverted
# setaf 2 = green, smso = inverted
set COLOR = `tput setaf 2; tput smso`

# back to normal screen colors
set NORMAL = `tput sgr0`

# print the time-date output on the above position
echo -n $COLOR$cmd$NORMAL

# restore the cursor to whatever was its previous position
echo -n -e "\033[u"

# script is executed every second
sleep 1
