Hi, I recently tried to create a tar archive on a Solaris 10 machine with gnu tar 1.17 and I used the command
gtar -cjf filename.tar file1 file2 directory.
The creation was successful but I'm not sure if the file was compressed with bzip as the
j option is supposed to do. How can I check that it was compressed?
I have tried the command
gtar -tf filename.tar and it lists all files but it doesn't say anything about compression (I left out the
j option on purpose to see if gtar would protest)
When I created the archive I thought that the
j option would add the
.bz2 extension to the file name but it didn't so now I'm confused...

Hmm, found the solution myself...
I ran
bunzip2 filename.tar and it didn't protest about file format (it warned about not being able to guess original file name).
Then I tried
bunzip2 somefile.txt and got the message
bunzip2: somefile.txt is not a bzip2 file.
Conclusion: my tar archive was compressed but the file name didn't reflect this and gtar can read a compressed archive even though I don't specify how it is compressed.
