FYI, if you run a command on command line, then you can easily get a log without resorting to screenshots. Example, contrived with ls:
ls -l /dev/* 2>&1 | tee log_ls.txt
The “2>&1” sets any error text to standard output, then the “| tee log_ls.txt” simultaneously prints the output to the end user as what the user would expect anyway, followed by writing a copy to “log_ls.txt” (use whatever log name you want).
