1. The query results of find /-type f-size + 1G files larger than 1G in the query server are as follows:

[root@localhost] # find /-type f-size + 1G / var/lib/mysql/darkindustry/tbl_jm_account.ibd / var/lib/mysql/tase1/key_timing_3.ibd / var/lib/mysql/tase1/news_info_bak_1.MYD / var/lib/mysql/mysql-bin.000001 / var/lib/mysql/aasl/7_quanliang_changeLocation.ibd / var/lib/mysql/jiema/tbl_account_pay_record.ibd / var/log/mysqld.log The command / home/local/mycat/logs/wrapper.log queries all files larger than 1G in size from the "/" root directory.

Related query: query files greater than 100m in the server

Find /-type f-size + 100M2, query the files greater than 1G in the server and the command for attribute information are as follows. When querying files larger than 1G, the creator, size (in b), modification date and path are displayed.

Find /-type f-size + 1G-print0 | xargs-0 ls-l query result is as follows:

[root@localhost ~] # find /-type f-size + 1G-print0 | xargs-0 ls-l-rw-r--r--. 1 root root 5777129059 March 17 16:29 / home/local/mycat/logs/wrapper.log-rw-. 1 root root 1214541824 February 20 2020 / usr/local/apache-tomcat-7.0.79/bin/core.32402-rw-r-. 1 mysql mysql 1157627904 December 19 10:48 / var/lib/mysql/aasl/7_quanliang_changeLocation.ibd-rw-r-. 1 mysql mysql 1119879168 April 15 2020 / var/lib/mysql/darkindustry/tbl_jm_account.ibd-rw-r-. 1 mysql mysql 14726201344 March 17 13:54 / var/lib/mysql/jiema/tbl_account_pay_record.ibd-rw-r-. 1 mysql mysql 1379945102 July 6 2020 / var/lib/mysql/mysql-bin.000001-rw-r-. 1 mysql mysql 5469372416 March 17 16:21 / var/lib/mysql/tase1/key_timing_3.ibd-rw-r-. 1 mysql mysql 2468393172 Jan 2 2020 / var/lib/mysql/tase1/news_info_bak_1.MYD-rw-r--r--. 1 mysql mysql 1859491887 March 17 16:12 / var/log/mysqld.log3, query and sort large files. Here, use du-h to display only the file size and path. To view details, change du-h to ls-l.

Find /-type f-size + 1G-print0 | xargs-0 du-h | the query result of sort-nr is as follows:

[root@localhost ~] # find / var/-type f-size + 1G-print0 | xargs-0 du-h | sort-nr 14G / var/lib/mysql/jiema/tbl_account_pay_record.ibd 5.4G / home/local/mycat/logs/wrapper.log 5.1G / var/lib/mysql/tase1/key_timing_3.ibd 2.3G / var/lib/mysql/tase1/news_info_bak_1.MYD 1.8G / var/log/mysqld.log 1.3G / var/lib/mysql/mysql-bin.000001 1.1g / var/lib/mysql/darkindustry/tbl_jm_account.ibd 1.1g / var/lib/mysql/aasl/7_quanliang_changeLocation.ibd like the above log log size of several gigabytes We usually change the configuration optimization or empty it, we usually use the echo "" > / var/log/mysqld.log command to clear it.
