I want to compile as fast as possible. Go figure. And would like to automate the choice of the number following the -j option. How can I programmatically choose that value, e.g. in a shell script?
I need to download a large file (1GB). I also have access to multiple computers running Linux, but each is limited to a 50kB/s download speed by an admin policy.
I have a small script that loops through all files of a folder and executes a (usually long lasting) command. Basically it’s
I have script I’d always like to run ‘x’ instances in parallel.
Is there any tool/command in Linux that I can use to run a command in more than one tab simultaneously? I want to run the same command: ./myprog argument1 argument2 simultaneously in more than one shell to check if the mutexes are working fine in a threaded program. I want to be able to increase the number of instances of this program so as to put my code under stress later on.
Suppose that I have three (or more) bash scripts: script1.sh, script2.sh, and script3.sh. I would like to call all three of these scripts and run them in parallel. One way to do this is to just execute the following commands:
Under the assumption that disk I/O and free RAM is a bottleneck (while CPU time is not the limitation), does a tool exist that can calculate multiple message digests at once?
