You should check up front if this file exists and bail if it does not.

Also check out the -K argument to curl to read options from a file (or stdin), which would avoid exposing your token in the output of ps.

Ya know, I kinda suspect that removing someone from the org removes their access rights to org repos so we may not need even need this.
