gzip not preserving file ownership 1

[philipose]

Gurus,
I am having a problem with preserving file ownership during gzip. The operating system is AIX 5.2 and the output of gzip -V is

gzip 1.2.4 (18 Aug 93)
Compilation options:
DIRENT UTIME STDC_HEADERS HAVE_UNISTD_H

The ownership of the file is not preserved after a gzip, but modification time and permissions are preserved. My understanding is that gzip preserves file ownerships too. If you have any thoughts or suggestions, please let me know. I do not have root permissions or superuser permissions.
Regards
Zacharia

You say not preserving ownership. So, for example, take a file:

rwxr-xr-x 3 oracle dba 512 May 6 04:40 control.idx

When you gzip it is no longer saving the oracle:dba perms? What are the owner perms? And is this when you decompress a gzip file?

gzip will only preserve ownership when run as root afaik.


HTH,

I disagree.

It preserves ownership even if you run with non-root user.

Phillipos,
What is the current ML level in your system. Check with
$instfix -i|grep ML
post the output of the above commmand.

I guess, in your case, you may have to apply ML or all files not installed for the current ML level. Check that out.

In my environment,we applied ML04 with critical patches. gzip works fine.
In your case, need to figure out which critical fix is required, can you post the following outputs.
#lslpp -h rpm.rte
#ls -l `which gzip`
#ls -l /usr/opt/freeware/bin/gzip

What about collecting the ownership/permission info into a script and include that in the zip?

Not perfect but works (I'm sure someone can improve on this)

ls -ld * | awk '{print "chown "$3":"$4,$9}' > file1

(see below for perms.ksh code)

perms.ksh *  > file2

ls -ld * | awk '{print $9}' > file3

paste file2 file3 > file4

sed -e 's/[put a tab in here]/ /' < file4 > file5

cat file1 file5 > sav.perms

#!/bin/ksh
ls -ld $* | 'BEGIN {
v["r1"]=400; v["w2"]=200; v["x3"]=100; v["s3"]=4100; v["S3"]=4000
v["r4"]=40 ; v["w5"]=20 ; v["x6"]=10 ; v["s6"]=2010; v["S6"]=2000
v["r7"]=4  ; v["w8"]=2  ; v["x9"]=1  ; v["t9"]=1001; v["T3"]=1000}
{val=0
for (i=1;i<=9;i++) val=val+v[substr($0,i+1,1)i]
printd "chmod""%4 %s\n",val,$NF}'
