root@clodb:/clodbvg>cat output.txt
root@clodb:/clodbvg>

output.txt is 0KB and there is nothing in it.


Whereas this

Code:
root@clodb:/clodbvg>(/opt/freeware/bin/tar -cvf -  /oratech | gzip > /clodbvg/bkp_21MAY16_oratech.tgz) > testoutput.txt 2>&1

Where's your backup file gone with the second version?

The first trial with tee fails because the files' names are listed to stderr, which doesn't make it into tee, and which you redirect in version 2. Still, you don't have the files on screen AND in testoutput as desired.

With my GNU bash, version 4.3.42(1)-release (x86_64-pc-linux-gnu), i came up with
Code:
tar cvf - fi* 2> >(tee ZZ /dev/tty) | gzip > XX 
file
file~
file1
file1~
file2
file2~
cat ZZ
file
file~
file1
file1~
file2
file2~

which seems to be close to what you requested.

With the second version, I will not see any output on the screen , it will be redirected to the file.

Rudic, for restore how would you do it ?

Backup
Code:
tar cvf - fi* 2> >(tee ZZ /dev/tty) | gzip > XX

Restore
Code:
.

Old 06-15-2016
Sort of (untested)
Code:
gunzip XX | tar xf -

Doesn't your tar version offer the -z option for creation and extraction of gzipped archives?

I'm inclined to bet there's <CR> chars involved.

sorry for misunderstanding, meant to say restore using tee command to capture the output like how wrote the command for backup..
so where to put
Code:
tee

command in your code
Code:
gunzip XX | tar xf -
