SGI IRIX (y'all have seen Jurassic Park, ya?) had this thing called
FAM, the File Access Monitor. Here's a really dumb version of that.
# --- 8< --- zFAM
# Example Usage
# coproc zFAM
# chpwd() { pwd -P >&p }
# precmd() { read -t 0 -p && print -ru2 -- $REPLY not readable }
typeset filename
read filename # Wait forever for first file to monitor
while [[ -n $filename ]]
do
if [[ -r $filename ]]
then
read -t 1 filename
else
print -r -- $filename
read filename
fi
done
