Find all files in entire server except /proc and /system

ultrakiasu · 07-01-2019, 02:18 AM

I am struggling to write a script to list out all the files in the solaris server and generate the the checksum of all the files.

find / -type f -exec digest -v -a md5 {} \; > /all_files_md5sum.txt

Since /proc and /system having some unreadable files, my script will hang indefinitely.

how could I achieve it on solaris11 with GNU find syntax with -path and -prune.
and also on legacy solaris10 with older non-GNU find?

Currently I am calling a script to filter out the /proc and /system via grep thru an external script
using

find / -type f -exec external_script {} \;

which contains:
dir=$1
echo $dir | grep ^/proc
if [ $? -eq 0 ]; then
exit
fi
echo $dir | grep ^/system
if [ $? -eq 0 ]; then
exit
fi
digest -v -a md5 $1 >> /all_files_md5sum.txt

Wouldn't it be the same for each system?

Code:

find ./ -path '/proc' -prune -o -path '/system' -prune \
    -o -type f -exec digest -a md5 {} \; > /all_files_md5sum.txt

You may have to exclude more than just those. What are you really looking for?

Nope...

Your syntax still listing /proc

Native Solaris 10 and Solaris 11, does not come with GNU find, thus there is no -path syntax in find.
The Supplement CD for Solaris 11 does include gnu find package, but solaris 10 it is too old and not included.

That was from the OpenBSD version, which also has -path. I guess it's been too long since I've looked at any Solaris.

I do not know if Solaris knows the -mount or -xdev option, but find with either option will NOT descend into mounted filesystems below the starting directory.
If there are any fs'es mounted which you DO want to search (i.e. /home) you will have to add them to the commandline, though:

Code:

find / /home -xdev -type f (etc.)

The -path and -prune stuff in post #2 works fine - if -path would be supported.
Note that for testing you must -print in the last -o branch; the implicit print does $ ... $ -print i.e. prints in all branches.

For the Solaris find I suggest to grep first.

Code:

#!/bin/sh
dirs=`
cd /
ls | fgrep -vx "\
proc
system"
`
(
cd /
# word-split on \n only
IFS=
# do not glob-match
set -f
find $dirs -type f -exec digest -a md5 {} \; > /all_files_md5sum.txt
)

The ( ) enforce a sub shell, so the IFS= and set -f and cd / do not impact a following main shell code.
(Also the ` ` is a sub shell, so its cd / won't impact the main shell.)

In bash you can use extglob rather than fgrep:

Code:

#!/bin/bash
(
shopt -s extglob
find /!(proc|system) -type f -exec digest -a md5 {} \; > /all_files_md5sum.txt
)

Again the ( ) limit the scope of the shopt -s extglob
