fish shell for loop oneliner

Question

I'm not sure how to do a for loop using fish shell. I keep having to drop out of fish to run it in bash.

take this for example:

for i in $(cat subdomains); do curl $i | html2text >> websites

I get:

fish: $(...) is not supported. In fish, please use '(cat)'.
for i in $(cat subdomains); do curl $i | html2text >> websites
         ^

Answer 1

Not an answer, but an extended comment.

Links to the relevant documentation:

• Command Substitutions
• for
• Variables
• Lists

Note that the command substitution will return a list of values representing each line of the command output. This makes it OK for you to use for line in (cat...) where that would be dodgy in bash.

Answer 2

for i in (cat subdomains); curl $i | html2text; end >> websites

is the answer
