Encrypt option not working in lrztar
opened this issue · comments
If I use the encrypt option with lrzip it works
lrzip --encrypt=1234 ~/.gnupg/gpg.conf Output filename is: ~/.gnupg/gpg.conf.lrz ~/.gnupg/gpg.conf - Compression Ratio: 0.149. Average Compression Speed: 0.000MB/s.
But trying to use it in lrztar results in
lrztar --encrypt=1234 ~/.gnupg /usr/bin/lrztar: illegal option -- - /usr/bin/lrztar: line 66: ((: v_?=1: syntax error: operand expected (error token is "=1") /usr/bin/lrztar: illegal option -- e /usr/bin/lrztar: line 66: ((: v_?=2: syntax error: operand expected (error token is "=2") /usr/bin/lrztar: illegal option -- r /usr/bin/lrztar: line 66: ((: v_?=5: syntax error: operand expected (error token is "=5") /usr/bin/lrztar: illegal option -- y /usr/bin/lrztar: line 66: ((: v_?=6: syntax error: operand expected (error token is "=6") tar: Removing leading /' from member names Unable to work from STDIO while reading password Fatal error - exiting
And the -e option results in a similar error in line 66
/usr/bin/lrztar: illegal option -- e /usr/bin/lrztar: line 66: ((: v_?=1: syntax error: operand expected (error token is "=1")
Since lrztar is a bash script i taken a look in line 66 and it shows the importation of lrzip arguments
((v_$x=${#vopt[@]}))
But from here and where that function goes... i can't see the "-e" argument. Is it missing or it was supposed to be passed automatically to lrzip?

EDIT: My excuses in advance for the lack of spaces, github is completely weird at text formatting.
No, encryption is not supported with lrztar because of the way it works. It's a braindead convenience wrapper and only using lrzip directly will give you access to all the features.
@ckolivas I tried to pipe it with tar cf, but lrzip says the following
Unable to work from STDIO while reading password
Is it a protection mechanism, just like lrztar not accepting this option?
How can I bypass it?
Unfortunately it's the same issue since lrztar uses stdio and stdio is the problem. It should be possible to pass the password on the command line though. I'll look into that. Otherwise you'll have to do it in two steps for now.
