系統(tǒng)大全為您提供Linux下的sort命令默認(rèn)將文件中的每一行為單位，進(jìn)行排序，然后輸出。具體地，就是從每行的第一個(gè)字符開始，依次按ASCII碼值進(jìn)行比較，最后將結(jié)果按升序排序輸出。1、sort常用選項(xiàng)?-u在排序的時(shí)候忽略相同的行，類似于uniq命令，不過(guò)uniq命令只能跳過(guò)相鄰的相同行，并不能進(jìn)行排序。-n按照數(shù)字大小排序，而不是文本的ascii碼順序。-r反序，也就是降序。-t指定列分隔符，注意這里的分隔符只能是一個(gè)字符，不能是多個(gè)字符，-t,--field-separator=SEPuseSEPinsteadofnon-blanktoblanktransition，默認(rèn)以非空到空的分隔作為列分隔符。-k指定排序關(guān)鍵字的列。-s有時(shí)候，sort會(huì)在根據(jù)指定字段排完序之后，自動(dòng)根據(jù)其他字段進(jìn)行resort，為了保證原來(lái)的數(shù)據(jù)記錄的順序，可以使用-s選項(xiàng)來(lái)禁止sort命令的resort機(jī)制。這里的-k選項(xiàng)比較復(fù)雜，這里單獨(dú)說(shuō)一下-k后面指定參數(shù)的格式：?12FStart.CStartModifier,FEnd.CEndModifier???開始部分????,??結(jié)束部分-k選項(xiàng)用來(lái)指定排序的關(guān)鍵字列，也就是排序依據(jù)的字段。-k后的參數(shù)格式大致分為兩個(gè)部分，開始部分和結(jié)束部分。開始部分中又可以看出三個(gè)參數(shù)：FStart、CStart和Modifier，其中FStart表示第第幾列（FStart表示FieldStart，也就是這個(gè)值用來(lái)指定排序依據(jù)所開始的列，列的序號(hào)從1開始，不是程序猿通常習(xí)慣的0），CStart表示第幾個(gè)字符（CharacterStart，就是說(shuō)這個(gè)值用來(lái)說(shuō)明排序依據(jù)從該列的第幾個(gè)字符開始，如果沒(méi)有指定，默認(rèn)從第一個(gè)字符開始），Modifier就是n、r等指定數(shù)值排序、逆序等的選項(xiàng)。與開始部分類似，結(jié)束部分也有三個(gè)參數(shù)：FEnd、CEnd和Modifier，其中FEnd就是指定排序依據(jù)到第幾列結(jié)束，CEnd指定排序依據(jù)到該列的第幾個(gè)字符結(jié)束，如果省略或者指定為0，則默認(rèn)到該域的最后一個(gè)字符，Modifier的含義和開始部分一樣。注意，如果沒(méi)有開始部分，則默認(rèn)從行首開始，如果省略結(jié)束部分，則默認(rèn)到行末結(jié)束。2、例子這里的例子用下面的文件作為例子：??12345678910111213$catname_list.txtaName:aGender:aProfession:aBirthday:aHeight:aEtc.aName:aGender:aProfession:aBirthday:aHeight:aEtc.AbbieCornishi:female:actor:19820807:1.73m:KlondikeHaraMikie:female:pictorialmodel:19870703:1.62m:OscarPromotionCo.,Ltd.DrewBarrymore:female:actor:19750222:1.63m:MusicandLyricsKobeBryant:male:NBAplayer:19780823:1.98m:LosAngelesLakersTimothyTheodoreDuncan:male:NBAplayer:19760425:2.11m:SanAntonioSpursTonyParker:male:NBAplayer:19820517:1.88m:SanAntonioSpursManuGinóbili:male:NBAplayer:19770728:1.98m:SanAntonioSpursLamarcusNuraeAldridge:male:NBAplayer:19850719:2.11m:PortlandTrailBlazersaName:aGender:aProfession:aBirthday:aHeight:aEtc.$?2.1常見的r，u，n選項(xiàng)的使用??1234567891011121314151617181920212223242526272829303132333435363738394041424344454647$sortname_list.txtAbbieCornishi:female:actor:19820807:1.73m:KlondikeaName:aGender:aProfession:aBirthday:aHeight:aEtc.aName:aGender:aProfession:aBirthday:aHeight:aEtc.aName:aGender:aProfession:aBirthday:aHeight:aEtc.DrewBarrymore:female:actor:19750222:1.63m:MusicandLyricsHaraMikie:female:pictorialmodel:19870703:1.62m:OscarPromotionCo.,Ltd.KobeBryant:male:NBAplayer:19780823:1.98m:LosAngelesLakersLamarcusNuraeAldridge:male:NBAplayer:19850719:2.11m:PortlandTrailBlazersManuGinóbili:male:NBAplayer:19770728:1.98m:SanAntonioSpursTimothyTheodoreDuncan:male:NBAplayer:19760425:2.11m:SanAntonioSpursTonyParker:male:NBAplayer:19820517:1.88m:SanAntonioSpurs?$sort-uname_list.txtAbbieCornishi:female:actor:19820807:1.73m:KlondikeaName:aGender:aProfession:aBirthday:aHeight:aEtc.DrewBarrymore:female:actor:19750222:1.63m:MusicandLyricsHaraMikie:female:pictorialmodel:19870703:1.62m:OscarPromotionCo.,Ltd.KobeBryant:male:NBAplayer:19780823:1.98m:LosAngelesLakersLamarcusNuraeAldridge:male:NBAplayer:19850719:2.11m:PortlandTrailBlazersManuGinóbili:male:NBAplayer:19770728:1.98m:SanAntonioSpursTimothyTheodoreDuncan:male:NBAplayer:19760425:2.11m:SanAntonioSpursTonyParker:male:NBAplayer:19820517:1.88m:SanAntonioSpurs?$sort-rname_list.txtTonyParker:male:NBAplayer:19820517:1.88m:SanAntonioSpursTimothyTheodoreDuncan:male:NBAplayer:19760425:2.11m:SanAntonioSpursManuGinóbili:male:NBAplayer:19770728:1.98m:SanAntonioSpursLamarcusNuraeAldridge:male:NBAplayer:19850719:2.11m:PortlandTrailBlazersKobeBryant:male:NBAplayer:19780823:1.98m:LosAngelesLakersHaraMikie:female:pictorialmodel:19870703:1.62m:OscarPromotionCo.,Ltd.DrewBarrymore:female:actor:19750222:1.63m:MusicandLyricsaName:aGender:aProfession:aBirthday:aHeight:aEtc.aName:aGender:aProfession:aBirthday:aHeight:aEtc.aName:aGender:aProfession:aBirthday:aHeight:aEtc.AbbieCornishi:female:actor:19820807:1.73m:Klondike?$sort-runame_list.txtTonyParker:male:NBAplayer:19820517:1.88m:SanAntonioSpursTimothyTheodoreDuncan:male:NBAplayer:19760425:2.11m:SanAntonioSpursManuGinóbili:male:NBAplayer:19770728:1.98m:SanAntonioSpursLamarcusNuraeAldridge:male:NBAplayer:19850719:2.11m:PortlandTrailBlazersKobeBryant:male:NBAplayer:19780823:1.98m:LosAngelesLakersHaraMikie:female:pictorialmodel:19870703:1.62m:OscarPromotionCo.,Ltd.DrewBarrymore:female:actor:19750222:1.63m:MusicandLyricsaName:aGender:aProfession:aBirthday:aHeight:aEtc.AbbieCornishi:female:actor:19820807:1.73m:Klondike2.2-k字段的使用（1）根據(jù)人名列表中出生年份字段排序出生年份就是出生年月的前四個(gè)字符。?123456789101112$sort-t:-k4,4.4nname_list.txt?aName:aGender:aProfession:aBirthday:aHeight:aEtc.aName:aGender:aProfession:aBirthday:aHeight:aEtc.aName:aGender:aProfession:aBirthday:aHeight:aEtc.DrewBarrymore:female:actor:19750222:1.63m:MusicandLyricsTimothyTheodoreDuncan:male:NBAplayer:19760425:2.11m:SanAntonioSpursManuGinóbili:male:NBAplayer:19770728:1.98m:SanAntonioSpursKobeBryant:male:NBAplayer:19780823:1.98m:LosAngelesLakersAbbieCor
