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
