Hi,

Use this:

find / -type f -name "k*" \( -perm -o+rx -o -perm -g+rx \)

Cheers,
K.

 

by: KeremEPosted on 2009-11-03 at 15:56:13ID: 25735210

or better:

find / -type f -name "k*" \( -perm -u+x -o -perm -o+x -o -perm -g+x \)

The first one did not look the creating owner and alsoo looked for Read along with Execute.

Cheers,
K.

Please make sure that you run the script as root otherwise you'll obviosly run in to these permission issues.

that worked

Shorter/easier to do

find / -type f -perm +0111 -ls

 

by: TintinPosted on 2009-11-03 at 17:27:21ID: 25735650

Sorry, forgot the k*, ie:

find / -type f -name "k*" -perm +0111 -ls

 

by: KeremEPosted on 2009-11-03 at 17:38:58ID: 25735684

From the Find man page:


      -perm +mode
             Deprecated,  old  way  of searching for files with any of the permission bits in mode set.  <layer id="google-toolbar-hilite-1" style="background-color: Dodgerblue; color: black;">You</layer> should use -perm /mode instead. Trying to use the + syntax with symbolic modes will yield surprising
             results.  For example, +u+x is a valid symbolic mode (equivalent to +u,+x, <layer id="google-toolbar-hilite-9" style="background-color: Fuchsia; color: black;"><layer id="google-toolbar-hilite-9" style="background-color: Fuchsia; color: black;"><layer id="google-toolbar-hilite-9" style="background-color: Fuchsia; color: black;">i</layer></layer></layer>.e. 0111) and will therefore not be evaluated as -perm +mode <layer id="google-toolbar-hilite-0" style="background-color: Chartreuse; color: black;">but</layer> instead as the exact mode specifier -perm mode  and  so
             it  matches files with exact permissions 0111 instead of files with any execute bit set.  If <layer id="google-toolbar-hilite-2" style="background-color: Dodgerblue; color: black;">you</layer> found this paragraph confusing, <layer id="google-toolbar-hilite-3" style="background-color: Dodgerblue; color: black;">you</layer>re not alone - just use -perm /mode.  This form of the -perm test
             is deprecated because the POSIX specification requires the interpretation of a leading + as being part of a symbolic mode, and so we switched to using / instead.

Just FYI

Your cut/paste isn't easy to read.

      -perm +mode
              Deprecated, old way of searching for files with any of the permission bits in mode  set.   You  should
              use  -perm  /mode  instead.  Trying  to  use  the '+' syntax with symbolic modes will yield surprising
              results.  For example, '+u+x' is a valid symbolic mode (equivalent  to  +u,+x,  i.e.  0111)  and  will
              therefore not be evaluated as -perm +mode but instead as the exact mode specifier -perm mode and so it
              matches files with exact permissions 0111 instead of files with any execute bit  set.   If  you  found
              this  paragraph  confusing,  you're  not alone - just use -perm /mode.  This form of the -perm test is
              deprecated because the POSIX specification requires the interpretation of a leading '+' as being  part
              of a symbolic mode, and so we switched to using '/' instead.


Simply a matter of changing to

find / -type f -name "k*" -perm /0111 -ls
