  • The coolest way I've found to backup a wordpress mysql database using encryption, and using local variables created directly from the wp-config.php file so that you don't have to type them- which would allow someone sniffing your terminal or viewing your shell history to see your info. I use a variation of this for my servers that have hundreds of wordpress installs and databases by using a find command for the wp-config.php file and passing that through xargs to my function.

    eval $(sed -n "s/^d[^D]*DB_\([NUPH]\)[ASO].*',[^']*'\([^']*\)'.*/_\1='\2'/p" wp-config.php) && mysqldump --opt --add-drop-table -u$_U -p$_P -h$_H $_N | gpg -er AskApache >`date +%m%d%y-%H%M.$_N.sqls`

  • You need to apt-get install python-sqlparse. This command simply formats a sql query and prints it out. It is very useful when you want to move a sql query from commandline to a shell script. Everything is done locally, so you don't need to worry about copying sql query to external websites. Show Sample Output


    1
    echo "select a, b, c from table where a = 3;"| python -c "import sys;import sqlparse;print sqlparse.format(sys.stdin.read(), reindent=True, keyword_case='upper')"

Designed to be easily parsed by scripts or other programs -list Query results will be displayed with the separator (|, by default) character between each field value. The default. From inside the command line this can be also changed using the mode command: .mode MODE ?TABLE? Set output mode where MODE is one of: csv Comma-separated values column Left-aligned columns. (See .width) html HTML code insert SQL insert statements for TABLE line One value per line list Values delimited by .separator string tabs Tab-separated values tcl TCL list elements Show Sample Output

  • This command will "su" the execution of the command to the postgres user(implies that you are already logger as root), and export the result of the query to a file on the csv format. You'll need to adequate the fields and database information to one of your choice/need. Show Sample Output
