nextflow executable is not executable on Linux

[bounlu]

When installing or upgrading nextflow, the executable is placed / overwritten at the /usr/local/bin/ directory. However, the permissions do not include read mode for the group and others:

-rwx--x--x 1 user staff 17K Feb 24 17:44 nextflow

In Linux, non-readable file is also non-executable, so if the server admin installs it as root, the other users cannot execute it by default. Every time it has to be given read access:

sudo chmod +r /us/local/bin/nextflow

-rwxr-xr-x 1 root root 17K Feb 18 14:48 nextflow

This is troublesome, and there should be a better way to handle this, or just give 755 for the executable by default.
