You need egrep to use | in expressions as gaurav said. Also, your scripting needs work, you forgot a | before grep, and you have to quote the expression to use | in it. You should also be escaping the .'s because . is a special character in regular expressions.

A sample line from the log file is:

the columns are tab delimited.
this works ok, except... (3 Replies)
Hi,
I am writing a shell script that checks catalina logs on a production system and mails me if it detects errors.
It greps the logs for known errors which i have defined as variables.
The problem is the logs are huge, approx 30,000 before they rotate.
So I am forced to use grep instead... (3 Replies)
The program that is running on my machine generates log files. I want to be able to know the number of lines that contain "FT" in the most recent log file. I wrote the following, but it always returns zero. And I know the count is not zero. Any ideas?
ls -rt *.log | tail -n 1 | grep -c FT (6 Replies)
I need to tail -f a file so I can monitor it as it is being written to. However, there is a lot of garbage in the file that I don't care about. So normally I would just pipe and grep for the string that is important to me. However, in this case, there are two things I need to grep for. I can't... (3 Replies)

save_binary_logs
SAVE_BINARY_LOGS(1p) User Contributed Perl Documentation SAVE_BINARY_LOGS(1p)NAME
save_binary_logs - Concatenating binary or relay logs from the specified file/position to the end of the log. This command is automatically
executed from MHA Manager on failover, and manual execution should not be needed normally.
SYNOPSIS
# Test
$ save_binary_logs --command=test --binlog_dir=/var/lib/mysql --start_file=mysqld-bin.000002
# Saving binary logs
$ save_binary_logs --command=save --binlog_dir=/var/lib/mysql --start_file=mysqld-bin.000002 --start_pos=312
--output_file=/var/tmp/aggregate.binlog
# Saving relay logs
$ save_binary_logs --command=save --start_file=mysqld-relay-bin.000002 --start_pos=312 --relay_log_info=/var/lib/mysql/relay-log.info
--output_file=/var/tmp/aggregate.binlog
save_binary_logs concatenates binary or relay logs from the specified log file/position to the end of the log. This tool is intended to be
invoked from the master failover script(MHA Manager), and manual execution is normally not needed.
DESCRIPTION
Suppose that master is crashed and the latest slave server has received binary logs up to mysqld-bin.000002:312. It is likely that master
has more binary logs. If it is not sent to the slave, slaves will lose all binlogs from mysqld-bin.000002:312. The purpose of the
save_binary_logs is to save binary logs that are not replicated to slaves. If master is reachable through SSH and binary logs are readable,
saving binary logs is possible.
Here is an example:
$ save_binary_logs --command=save --start_file=mysqld-bin.000002 --start_pos=312 --output_file=/var/tmp/aggregate.binlog
Then all binary logs starting from mysqld-bin.000002:312 are concatenated and stored into /var/tmp/aggregate.binlog. If you have binary
logs up to mysqld-bin.000004, the following mysqlbinlog outputs are written.
mysqld-bin.000002:Format Description Event(FDE), plus from 312 to the tail mysqld-bin.000003:from 0 to the tail, excluding FDE
mysqld-bin.000004:from 0 to the tail, excluding FDE
