apropos: Linux中除man以外很強大的協助命令 Linux中協助一直使用man,但前提是知道這個命令怎麼寫。 如果遇到想完成某個功能,但具體命令忘了的時候怎麼辦能。 新發現從來也沒用過的apropos, 直接輸入apropos [keyword], 即可查看與keyword相關功能的命令。 該命令實際完成的是搜尋其它命令的描述資訊,將相關命令羅列出來,不一定出現的命令就是想要的,但可以從中協助回憶到有用的命令。 apropos 使用方法 man apropos 自己看。 apropos 例子 用apropos尋找和sort相關的命令: apropos sort alphasort [scandir]  (3)  - scan a directory for matching entriesbsearch              (3)  - binary search of a sorted arraybsearch              (3p)  - binary search a sorted tablebunzip2              (1)  - a block-sorting file compressor, v1.0.2bunzip2 [bzcat]      (1)  - a block-sorting file compressor, v1.0.2bunzip2 [bzip2]      (1)  - a block-sorting file compressor, v1.0.2bunzip2 [bzip2recover] (1)  - a block-sorting file compressor, v1.0.2bzip2                (1)  - a block-sorting file compressor, v1.0.2bzip2 [bunzip2]      (1)  - a block-sorting file compressor, v1.0.2bzip2 [bzcat]        (1)  - a block-sorting file compressor, v1.0.2bzip2 [bzip2recover] (1)  - a block-sorting file compressor, v1.0.2comm                 (1)  - compare two sorted files line by lineiterator_info_s [netsnmp_iterator_info_s] (3)  - Holds iterator information containing functions which should be called by the iterator_handler to loop over your data set and sort it in a SNMP specific mannerldap_sort_entries    (3)  - LDAP sorting routinesldap_sort_entries [ldap_sort] (3)  - LDAP sorting routinesldap_sort_entries [ldap_sort_strcasecmp] (3)  - LDAP sorting routinesldap_sort_entries [ldap_sort_values] (3)  - LDAP sorting routinesldap_sort_strcasecmp (3)  - LDAP sorting routinesldap_sort_strcasecmp [ldap_sort] (3)  - LDAP sorting routinesldap_sort_strcasecmp [ldap_sort_entries] (3)  - LDAP sorting routinesldap_sort_strcasecmp [ldap_sort_values] (3)  - LDAP sorting routinesldap_sort_values     (3)  - LDAP sorting routinesldap_sort_values [ldap_sort] (3)  - LDAP sorting routinesldap_sort_values [ldap_sort_entries] (3)  - LDAP sorting routinesldap_sort_values [ldap_sort_strcasecmp] (3)  - LDAP sorting routineslsort                (n)  - Sort the elements of a listqsort                (3)  - sorts an arrayqsort                (3p)  - sort a table of datasort                 (1)  - sort lines of text filessort                 (1p)  - sort, merge, or sequence check text filessort                 (3pm)  - perl pragma to control sort() behaviourtexindex             (1)  - sort Texinfo index filestsort                (1)  - perform topological sorttsort                (1p)  - topological sortuniq                 (1)  - remove duplicate lines from a sorted fileversionsort [scandir] (3)  - scan a directory for matching entries
