| Theodore Ts'o | f9ddad5 | 2003-04-14 18:05:12 -0400 | [diff] [blame] | 14 | .SH DESCRIPTION |
| 15 | The |
| 16 | .B logsave |
| 17 | program will execute |
| Theodore Ts'o | bc34d6b | 2003-04-16 14:05:06 -0400 | [diff] [blame] | 18 | .I cmd_prog |
| 19 | with the specified argument(s), and save a copy of its output to |
| Theodore Ts'o | f9ddad5 | 2003-04-14 18:05:12 -0400 | [diff] [blame] | 20 | .IR logfile . |
| 21 | If the containing directory for |
| 22 | .I logfile |
| 23 | does not exist, |
| 24 | .B logsave |
| 25 | will accumulate the output in memory until it can be written out. |
| 26 | A copy of the output will also be written to standard output. |
| 27 | .PP |
| 28 | If |
| Theodore Ts'o | bc34d6b | 2003-04-16 14:05:06 -0400 | [diff] [blame] | 29 | .I cmd_prog |
| Theodore Ts'o | f9ddad5 | 2003-04-14 18:05:12 -0400 | [diff] [blame] | 30 | is a single hyphen ('-'), then instead of executing a program, |
| 31 | .B logsave |
| Theodore Ts'o | bc34d6b | 2003-04-16 14:05:06 -0400 | [diff] [blame] | 32 | will take its input from standard input and save it in |
| 33 | .I logfile |
| Theodore Ts'o | f9ddad5 | 2003-04-14 18:05:12 -0400 | [diff] [blame] | 34 | .PP |
| 35 | .B logsave |
| 36 | is useful for saving the output of initial boot scripts |
| 37 | until the /var partition is mounted, so the output can be written to |
| 38 | /var/log. |
| 39 | .SH OPTIONS |
| 40 | .TP |
| 41 | .B \-a |
| 42 | This option will cause the output to be appended to |
| 43 | .IR logfile , |
| Theodore Ts'o | bc34d6b | 2003-04-16 14:05:06 -0400 | [diff] [blame] | 44 | instead of replacing its current contents. |
| 45 | .TP |
| 46 | .B \-s |
| 47 | This option will cause |
| 48 | .B logsave |
| 49 | to skip writing to the log file text which is bracketed with a control-A |
| 50 | (ASCII 001 or Start of Header) and control-B (ASCII 002 or Start of |
| 51 | Text). This allows progress bar information to be visible to the user |
| 52 | on the console, while not being written to the log file. |
