[Gambas-user] Shell command not working

[Jose Monteiro]

text = "cd ~/.relat_bact && rm -rf Modelo*.odt && zip -r " & "MA" & Mid$(ListBox1.Text, 1, 9) & ".odt  ."
  Shell text Wait

1 - navigating to ~/.relat_bact directory and deleting the odt file is working fine.

2 - generating the "zipped" odt file (MAxxxx.odt) using the files and directories inside ~/.relat_bact is not working. The error message is: "zip I/O error: No such file or directory
zip error: Could not create output file (MA000004/12.odt)"

3 - If I type these commands directly on a terminal it works fine.
