The command "singularity run ${image-sif}" is used to execute a Singularity container image.
Here's the breakdown of the command:
-
"singularity": This is the command to interact with Singularity, a containerization tool similar to Docker but specifically designed for scientific and HPC workloads.
-
"run": This sub-command instructs Singularity to run the container.
-
"${image-sif}": This is a placeholder for the path or name of the Singularity container image file in SIF format (the default format for Singularity images). It's enclosed in curly braces and prefixed with a dollar sign ($), indicating it's a shell variable. You need to replace "${image-sif}" with the actual path or name of the image file you want to run.
By running this command, Singularity will start a new process using the specified Singularity container image and execute the programs or scripts contained within the image.
