Maintained by C. Spieler. Send bug reports using http://www.info-zip.org/zip-bug.html; see README for details. Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir] Default action is to extract files in list, except those in xlist, to exdir; file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage). -p extract files to pipe, no messages -l list files (short format) -f freshen existing files, create none -t test compressed archive data -u update files, create if necessary -z display archive comment only -v list verbosely/show version info -T timestamp archive to latest -x exclude files that follow (in xlist) -d extract files into exdir modifiers: -n never overwrite existing files -q quiet mode (-qq => quieter) -o overwrite files WITHOUT prompting -a auto-convert any text files -j junk paths (do not make directories) -aa treat ALL files as text -U use escapes for all non-ASCII Unicode -UU ignore any Unicode fields -C match filenames case-insensitively -L make (some) names lowercase -X restore UID/GID info -V retain VMS version numbers -K keep setuid/setgid/tacky permissions -M pipe through "more" pager -O CHARSET specify a character encoding for DOS, Windows and OS/2 archives -I CHARSET specify a character encoding for UNIX and other archives See "unzip -hh" or unzip.txt for more help. Examples: unzip data1 -x joe => extract all files except joe from zipfile data1.zip unzip -p foo | more => send contents of foo.zip via pipe into program more unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer [root@localhost plugins]# unzip elasticsearch-analysis-ik-7.4.2.zip Archive: elasticsearch-analysis-ik-7.4.2.zip inflating: elasticsearch-analysis-ik-7.4.2.jar inflating: httpclient-4.5.2.jar inflating: httpcore-4.4.4.jar inflating: commons-logging-1.2.jar inflating: commons-codec-1.9.jar inflating: plugin-descriptor.properties inflating: plugin-security.policy creating: config/ inflating: config/surname.dic inflating: config/quantifier.dic inflating: config/extra_stopword.dic inflating: config/suffix.dic inflating: config/extra_single_word_full.dic inflating: config/extra_single_word.dic inflating: config/preposition.dic inflating: config/IKAnalyzer.cfg.xml inflating: config/main.dic inflating: config/stopword.dic inflating: config/extra_main.dic inflating: config/extra_single_word_low_freq.dic [root@localhost plugins]# ll total 5828 -rw-r--r-- 1 root root 263965 May 6 2018 commons-codec-1.9.jar -rw-r--r-- 1 root root 61829 May 6 2018 commons-logging-1.2.jar drwxr-xr-x 2 root root 299 Oct 7 2019 config -rw-r--r-- 1 root root 54643 Nov 4 2019 elasticsearch-analysis-ik-7.4.2.jar -rw-r--r-- 1 root root 4504487 Jun 15 13:13 elasticsearch-analysis-ik-7.4.2.zip -rw-r--r-- 1 root root 736658 May 6 2018 httpclient-4.5.2.jar -rw-r--r-- 1 root root 326724 May 6 2018 httpcore-4.4.4.jar -rw-r--r-- 1 root root 1805 Nov 4 2019 plugin-descriptor.properties -rw-r--r-- 1 root root 125 Nov 4 2019 plugin-security.policy [root@localhost plugins]# mkdir ik [root@localhost plugins]# ll total 1428 -rw-r--r-- 1 root root 263965 May 6 2018 commons-codec-1.9.jar -rw-r--r-- 1 root root 61829 May 6 2018 commons-logging-1.2.jar drwxr-xr-x 2 root root 299 Oct 7 2019 config -rw-r--r-- 1 root root 54643 Nov 4 2019 elasticsearch-analysis-ik-7.4.2.jar -rw-r--r-- 1 root root 736658 May 6 2018 httpclient-4.5.2.jar -rw-r--r-- 1 root root 326724 May 6 2018 httpcore-4.4.4.jar drwxr-xr-x 2 root root 6 Jun 15 13:17 ik -rw-r--r-- 1 root root 1805 Nov 4 2019 plugin-descriptor.properties -rw-r--r-- 1 root root 125 Nov 4 2019 plugin-security.policy [root@localhost plugins]# mv * ik/ mv: cannot move ‘ik’ to a subdirectory of itself, ‘ik/ik’

但是有很多的词识别不了，需要自定义词汇表
