How to Improve find Performance

• For performance reasons, put the-exec operator closer to the back, the better. This can avoid unnecessary processes.

• The find Command needs to read each index node in the directory tree it searches for, so it is best to combine multiple contents into a single find command as much as possible. The method is

  find . \( -type d    -a -exec chmod 771 {} \; \) -o     \( -name "*.BAK" -a -exec chmod 600 {} \; \) -o     \( -name "*.sh" -a -exec chmod 755 {} \; \) -o     \( -name "*.txt" -a -exec chmod 644 {} \; \) -o \

• To improve the efficiency of find, you can consider creating your own find database.

  Create a find Database

  Cdfind.-print | sed "[email protected] ^./@"> ~ /. Fastfinddb # Storage ~ /, And replace it ./

  Create cron and run this script regularly to create the find database.

  Create a shell script to use this database

  Ffind () {egrep "$1 "~ /. Fastfinddb | sed "[email protected] ^ @ $ home/@" # add $ home before the query result}
