The following is often used to set file permissions, a good example being setting a key file to an appropriate permission level to be used by ssh (this being the "octal" form):
chmod 600 filename.xyz
Would it be a correct equivalent and acceptable practice to use the following instead (this is the "symbolic" form)?
chmod a=,u=r filename.xyz
The reason I ask is that it seems a bit clearer for code readability. Still not exactly human readable, but no bit mapping needed.
If maximum readibility (and not terseness) were the primary driver, would there be a better option?
chmod a=,u=r filename.xyz
it is easy to read.
