I have a csv file which includes a bunch of commands in the command line. I can just bash this csv file, but the commands will be executed sequentially in the same terminal. Is there a way to execute each one of these commands in a separate terminal, so that they are executed in parallel?
Example:
It's like:
python args1
python args2
...
python argsn
If you want to do any serious software development on a Mac, I would suggest you install homebrew because Apple doesn't ship a package manager, but does ship ancient versions of all the tools most people use... Python, sed, PHP, Perl, awk, find, grep, make, git...
Once you have homebrew, I would recommend GNU Parallel which you can install with:
brew install parallel
Once you have GNU Parallel, you can run your commands in parallel with:
parallel --dry-run -a commands.csv
Or, maybe you would like the lines tagged with their names:
parallel --tag -a commands.csv
If you would like 8 to run at a time, add -j 8. If you want an Estimated Time of Arrival (when they should complete) add --eta and so on.
By the way, you can look for other tools, like Intel TBB, with:
brew search tbb
or pango, with:
brew search pango
--dry-run--line-buffer or --ungroup to get output sooner. You can also add --job-log YourLog.txt to get a log file.You basically just have a shell script already. The only difference is that instead of running it as one script, you want to run each line as a separate command. How you open a new terminal is somewhat OS-dependent, but let's assume you would just use the xterm command. The following will treat your script commands.csv (or whatever it is named) as a data file.
while IFS= read -r cmdline; do
xterm -e sh -c "$cmdline" &
done < commands.csv
osx; checking how you would use the standard Terminal app instead of xterm.)
You can run commands in the background like
run-command &
run-some-other-command &
etc &
is that something you can use?
csv?
