File read

This executable can read data from local files.
  1. This function can be performed by any unprivileged user.
    w3m -dump /path/to/input-file
    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 ....
    w3m -dump /path/to/input-file
    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.
    w3m -dump /path/to/input-file
    RemarksThe content is corrupted or otherwise altered by the process, thus it might not be suitable for handling arbitrary binary data.
