UNIX for Dummies Questions & Answers

Hi ,

We are migrating our scripts from one unix server to another unix server in aix. Is there any way we can export the permissions, owner, group of the folders and files inside the folders.

If I am copying xyz folder from old server, I need to generate a report with permissions ,owner and group for all the folders and files under xyz, same script I have to execute it in new server and compare.

Is there any utility for do this.

you can try something like below in awk or sed

This is not the correct syntax..just for giving you an idea.

ls -lstr | awk 'print $2,$3...(which all feilds you want) > file.csv comma separated file

run the same script in another box..

If you want a quick way to check, dump all the ls -lh output into a file on each server and cksum the resulting files. If there is a difference, you could diff them to see where the differences are.
Edited to add: You need to filter out the date and time columns using awk as suggested above for this to work properly.

What are you using to migrate everything? You might look at rsync, it keeps all permissions etc intact during a move.

In addition to owner and group name, will each user retain their original numeric UID and GID - or are they different on the new computer?

What software do you have available to copy the files?

Hi ,

I am using the below script for generating my report...it is generating duplicate entries , and I am not able to capture owner and user info...pls tell what is wrong in the script.

Code:

!/usr/bin/

# directories
dirs=$(find . -type d | sed "s/^.\///")

nowdir=$PWD
# filelist / dir
echo "$dirs" | while read dir
do
        cd "$nowdir/$dir"
        files=$(find . -type f | sed "s/^.\///")
        echo "$files" | while read file
        do
                echo "$dir;$file"
        done
done

Difficult to guess what your output should look like.
I guess you mean something like this (untested on AIX - may need adjustment):

Code:

find . -print|sort| while read F
do
          ls -lad "${F}"|tr -s " "|cut -d" " -f1-5,9-
done

The idea is to do a directory listing on each file or directory but miss out the file timestamp fields. The "sort" is needed because you can't guarantee that "find" will descend the old and new trees in the same order.

If you redirect the output of the script to a file you can copy that file and the script to you new server, run the script again on your new server and compare the output. Expect to get some subtle differences (like the size of directory files).

Personally I'd make every effort to preserve the timestamps of the files and compare those too. You can't preserve the timestamps of directories by any easy method.
