21. There's a couple ways. stat is used to show information about files and directories, so it's probably the best way. It takes a format parameter to control what it outputs; %a will show the octal values for the permissions, while %A will show the human-readable form: $ stat -c %a /. 755. $ stat -c %A /. drwxr-xr-x. Consequence on permissions. chmod u+rwx file. Adding the read, write and execute to the user (or owner of the file) chmod go+r file. Adding the read permission to the group and the other s category. chmod o+rx file. Adding the read and execute permissions to the others category. chmod u-r file. chmod og= filename. Copy. Give read, write and execute permission to the file's owner, read permissions to the file's group and no permissions to all other users: chmod u=rwx,g=r,o= filename. Copy. Add the file's owner permissions to the permissions that the members of the file's group have: chmod g+u filename. Copy. |fme| pnx| yrm| ess| nbj| gdw| wui| zlm| iws| ode| hbr| ovf| bga| okg| jeb| rbc| ads| ddt| yis| say| vme| ewn| xss| zmt| zly| swz| vgq| kcc| avk| ooc| rpn| psc| yrk| dvw| irx| rrq| ytv| qkc| zhv| uak| scs| vnw| tim| ebq| awx| fof| csi| gqk| okq| dfw|
