UNIX for Dummies Questions & Answers

Sorry, remove the echo in my command line (left in from "debugging", my fault); would it then mv files? If not, please give us the output of

Code:

for i in /source/dir/*20120420??????; do echo $i; done;

(I assume you replaced /source/dir with your respective source directory)

btw, the tar -z option will zip the archive on the fly.

Hi RudiC,

Here is the command I ran:
I'm simulating with this created directories. I have 3 files in /home/oracle/work/adams_de/source and /home/oracle/work/adams_de/target - the target directory.

Below is the error I get:
- but all those directories exist.

I just tested both directories earlier and I have access to them.

Thanks a lot.

And for your info I'm running on AIX 6.

option -z for tar doesn't work on AIX 6. And one more thing, I tried with both and - the trailing forward slash but same error.

RudiC,

Sorry my mistake, now they were moved to the target directory but not tar and compressed.

I didn't check as I got that error.

OK, so the

Code:

for i in /home/oracle/work/adams_de/source/*20120630??????; do mv $i  /home/oracle/work/adams_de/target ; done;

seems to work.
Next step: tar'ring. Your tar command

Code:

tar -cvf 30jun2012.tar  /home/oracle/work/adams_de/target/ gzip 30jun2012.tar

looks a bit strange to me, ar least the gzip should be separated with a ;. AFAIK tar writes to standard output if no archive file given and thus you can pipe that to gzip. Try the following:

Code:

tar -cv  /home/oracle/work/adams_de/target/|gzip > /dest/dir/30jun2012.tgz

You need to tell it - as the filename to make it write to stdout, and that's only for some implementations of tar.

That's what I remembered as well; but my linux version does it without -, in fact - gives an error. So Creems needs to test which one will work for him on his AIX. Another option would be to use tar's -O option, this would definitely tar to stdout.

*shrug* My linux version doesn't, my Linux version needs it, and it's just ordinary GNU tar. Maybe you're using something odd like busybox tar, or some sort of wrapper script. Most tars will complain if you don't give it some sort of output option like -f.

On systems which don't support -, you may have to do something kludgy like /proc/self/fd/1.

You got me confused. But, from this forum's linux man page:
which is what I get running tar.
