logsave - Unix, Linux Command
NAME
logsave: save output of a Linux command to a file.
SYNOPSIS
DESCRIPTION
logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output to logfile. If the containing directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out. A copy of the output will also be written to standard output. If cmd_prog is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in logfile logsave is useful for saving the output of initial boot scripts until the /var partition is mounted, so the output can be written to /var/log.
Options
| Tag | Description |
|---|---|
| -a | This option will cause the output to be appended to logfile, instead of replacing its current contents. |
| -s | This option will cause logsave to skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of Header) and control-B (ASCII 002 or Start of Text). This allows progress bar information to be visible to the user on the console, while not being written to the log file. |
| -v | This option will make logsave to be more verbose in its output to the user. |
EXAMPLES
