'%logstart name' saves to file 'name' in 'backup' mode. It saves your history up to that point and then continues logging. %logstart takes a second optional parameter: logging mode. This can be one of (note that the modes are given unquoted): append Keep logging at the end of any existing file. backup Rename any existing file to name~ and start name. global Append to a single logfile in your home directory. over Overwrite any existing log. rotate Create rotating logs: name.1~, name.2~, etc. Options: -o log also IPython's output. In this mode, all commands which generate an Out[NN] prompt are recorded to the logfile, right after their corresponding input line. The output lines are always prepended with a '#[Out]# ' marker, so that the log remains valid Python code. Since this marker is always the same, filtering only the output from a log is very easy, using for example a simple awk call:: awk -F'#\[Out\]# ' '{if($2) {print $2}}' ipython_log.py -r log 'raw' input. Normally, IPython's logs contain the processed input, so that user lines are logged in their final form, converted into valid Python. For example, %Exit is logged as _ip.run_line_magic("Exit"). If the -r flag is given, all input is logged exactly as typed, with no transformations applied. -t put timestamps before each input line logged (these are put in comments). -q suppress output of logstate message when logging is invoked Zortqortqbackupz# IPython log file zCouldn't start log: %sF outputNTzGActivating auto-logging.
