View all MySQL Variables for Pasting into my.cnf

This is really useful for me because I work with dozens of different database servers. The first thing I do is run this command and paste it into the servers /etc/my.cnf file. That way I will always know the original value and it just makes life much easier.

Command to run in Shell

$ mysql -NBe 'SHOW VARIABLES' | sed 's,\t,^=,' | column -ts^ | tr "\n" '@' | eval $(echo "sed '" "s,@\("{a..z}"\),\n\n\1,;" "'") | tr '@' "\n" | sed 's,^,# ,g'

View MySQL Variables Command

Run this ( setup your ~/.my.cnf file first ) in bash and it will save the output in ~/mysql-variables.log, suitable for instantly pasting in the main server conf file with vim.

{ echo -e "# MYSQL VARIABLES {{{1\n##\n# MYSQL `mysql -V|sed 's,^.*\(V.*\)\, for.*,\1,'` - By: `logname`@`hostname -f` on `date +%c`\n##"; for l in {a..z}; do echo '#'; mysql -NBe "SHOW GLOBAL VARIABLES LIKE '${l}%'" | sed 's,\t,^= ,' | column -ts^ | tr "\n" '@' | eval $(echo "sed '" "s,@\("{a..u}{a..z}"\),\n\n\1,;" "'") | eval $(echo "sed '" "s,@\(innodb_"{a..z}{a..z}"\),\n\n\1,;" "'") | tr '@' "\n" | sed 's,^,# ,g'; done; echo -e "#\n##\n# MYSQL VARIABLES }}}1"; } | tee ~/mysql-variables.log

Newlines before each group!

# MYSQL VARIABLES {{{1
##
# MYSQL Ver 15.1 Distrib 5.5.31-MariaDB - By: srot@host.askapacherack.com on Wed Jul 10 20:53:49 2013
##
#
# aria_block_size                           = 8192
#
# aria_checkpoint_interval                  = 30

Improved Command for VIM

{ echo -e "# MYSQL VARIABLES @ `hostname -f` ON `date +%c` {{{1\n#######"; mysql -NBe 'SHOW VARIABLES' | sed 's,\t,^=,' | column -ts^ | tr "\n" '@' | eval $(echo "sed '" "s,@\("{a..z}"\),\n\n\1,;" "'") | tr '@' "\n" | sed 's,^,# ,g'; echo -e "######\n# MYSQL VARIABLES }}}1"; }

Command Breakdown

  1. Show all Variables using Batch Mode
    mysql -NBe 'SHOW VARIABLES'
  2. Remove tabs and add the '^='
    sed 's,\t,^=,'
  3. Align the left column of varnames and the right column of values
    column -ts^
  4. Replace the end-of-line with '@'
    tr "\n" '@'
  5. Add 3 blank lines before the first occurance of each letter in the alphabet
    eval $(echo "sed '" "s,@\("{a..z}"\),\n\n\1,;" "'")
  6. Replace '@' with newlines
    tr '@' "\n"
  7. Make every line commented by '# '
    sed 's,^,# ,g'
