List, How can I check the permissions of all the files of my CentOS server? I'm looking for some kind of report with this information.. Is there some command? Some tool?

Here is a command that will give you the entire list of all files on your system in the format: "user:group mode path"

$ find / -printf "%u:%g %m %p\n"

Note that it _will_ cross filesystems, including any NFS mounts. Use the "-mount" option to keep it from crossing filesystems.

If you want to create a script to reapply all standard UNIX permissions to all files in a tree, here is a script (saveperm.sh) that outputs such a script:

#!/bin/bash mydir="${1}" if [ "${mydir}" == "" ]; then echo "Syntax: " echo " saveperm.sh (path)" echo "NOTE: saveperm.sh does not cross filesystems" echo "NOTE: saveperm.sh does not handle spaces in filenames" exit 127 fi if [ ! -d "${1}" ]; then echo "${1} is not a directory" exit 127 fi echo "#!/bin/bash" echo "# Created by saveperm.sh" echo "# Run from `pwd` targeting ${mydir}" echo "" for mypath in `find ${mydir} -mount`; do find "${mypath}" -maxdepth 0 -printf "chown %u:%g %p\n" find "${mypath}" -maxdepth 0 -printf "chmod %m %p\n" done

You'd typically run it with (examples):

$ saveperm.sh /abspath > /perms_abspath.sh [ save absolute path /abspath to a script /perms_abspath.sh ]

$ saveperm.sh . > ../perms_subdir.sh [ save perms on current directory to script perms_subdir.sh in parent ]

The above script outputs (echos) a script to the screen. You can redirect that into a file for execution later.

Note that the above script will NOT handle spaces in filenames! I have found different bash versions to be exceedingly difficult in handling spaces in filenames when returning from a find. Setting IFS="\n" typically doesn't work well or consistently. I would use an equivalent tcsh script instead of dorking with bash.**
