Fish is great!! I switched over from bash recently and I am really loving
fish. So well made, such a pleasure to use. I've been using bash for many
years, and I probably haven't been using its full power. I like that fish
works so well without having to enable features or customize.
I do find this statement odd though, "fish is a user friendly commandline shell
intended mostly for interactive use". As far as I can tell (I've only written
one shell script in fish so far), it is just as awesome for writing shell
scripts as it is for interactive use. Am I missing something?
Thanks to all the fish developers.
I do not belong to the emai list, so please reply to my email address. Thanks.
Here is a little shell script for you:
#!/usr/bin/fish
# Usage: countdown <minutes> OR countdown -s <seconds>
switch $argv[1] # set $delay to the countdown time in seconds
case -s # seconds
set delay $argv[2]
case '*' # minutes
set delay (expr $argv[1] \* 60)
end
for i in (seq $delay -1 0) # count down the time
set text (date -d"0+$i sec" +%H:%M:%S)
/bin/echo -ne "\r$text"
sleep 1
end
/bin/echo -e "\rDONE! ";
