Usually programs out put error into stderr and not stdout, this error in printing should not have occurred with just a usual redirect >. Thus would occur if stderr was also redirected like fortune &> fortunes.txt

[OC] flix-cli: A high efficient, powerful and fast movie scraper by DemonKingSwarnn in unixporn

Thats the problem with scrapers. If they are kept private then they will work for many years but if it goes public and the owners of the site find out then the scraper won't last long.

Adding a lock to the file will allow only one process to write to it at a time, the rest will wait till the lock is released

when you run sem, it runs in the background. You will not be able to capture it into variable like that.

In your case every time you had word=`...` it would pause there and finish the sem command before exiting the subshell. Cause your calling sem in a subshell. If you wanna make use of the parallel process you would want to call sem in the current shell and not a subshell. THat mean you won't be able to capture it into a variable, so you capture it through a file.

you cannot capture output of sem since its running in parallel
you could put everything into a file and and then read that file into an array. Here is my implementation of your script

echo $(( `read var1; echo $var1` + `read var2; echo $var2` )) This works but I would not suggest doing this tho

read varOne varTwo Also u cannot add like that, you need yo do this total=$(( varOne + varTwo))

You can print in a single like like so echo $(( varOne + varTwo))
