Use Cases
- You are collaborating with another researcher on a data set and you want to make sure all files are editable by the both of you. You need to make sure group read/write permissions are enabled and you both belong to a common group.
- Your research group maintains a central data repository and different members are responsible for processing subjects at different stages. But everyone needs access to all the files created. Use this to make sure read/write permissions are enabled on that centrally located directory for the group.
Help/Usage
$ fix_perms.sh --help fix_perms.sh This tool changes the permissions of any file owned by the executing user to have group read/write/execute permissions. Given no arguments, this permissions change is done recursively on the current directory. Given an argument that points to a directory that exists in the filesystem, it will run recursively on that. USAGE: $ fix_perms.sh -h or $ fix_perms.sh --help To see this usage message. $ fix_perms.sh Will recursively search the current working directory for files owned by the executing user. Any files that do not have group read/write/execute permissions will be given such. $ fix_perms.sh /path/to/directory Will recursively search the directory given as an argument for files owned by the executing user. Any files that do not have group read/write/execute permission will be given such. $ fix_perms.sh -q /path/to/directory Will do the same changing of permissions, but suppress the output of the find and chmod commands so that the process happens quietly. Useful if you run this command on directories everytime you login as a background process and would like to not be bombarded by lines and lines of output.
