Logging
termscp writes a log file for each session, located at:
$HOME/.cache/termscp/termscp.logon Linux/BSD$HOME/Library/Caches/termscp/termscp.logon macOSFOLDERID_LocalAppData\termscp\termscp.logon Windows
The log is not rotated: it is truncated on each launch of termscp. If you want to report an issue and attach the log file, save the log somewhere safe before launching termscp again.
By default the log reports at the INFO level, so it is not very verbose.
Reproducing an issue at TRACE level
To submit an issue, reproduce the problem with the log level set to TRACE by
launching termscp with the -D CLI option.
Disabling logging
To turn logging off, start termscp with the -q or --quiet option. You can
alias termscp to make it persistent.
Security
The log file does not contain any plaintext password. It exposes the same
information as the sibling bookmarks file.
