如何从文件中的同一行删除下面的重复项?我需要删除重复项，包括分号。
例如，从下面的文件输出中，我只需要"dg01.server.wmq.host=jms1001-01-ri5.ri5.dc2.responsys.com"类似地，文件的其他行。
dg01.server.wmq.host=jms1001-01-ri5.ri5.dc2.responsys.com;jms1001-02-ri5.ri5.dc2.responsys.com dg02.server.wmq.host=jms1002-01-ri5.ri5.dc2.responsys.com;jms1002-02-ri5.ri5.dc2.responsys.com dg03.server.wmq.host=jms1003-01-ri5.ri5.dc2.responsys.com;jms1003-02-ri5.ri5.dc2.responsys.com dg04.server.wmq.host=jms1004-01-ri5.ri5.dc2.responsys.com;jms1004-02-ri5.ri5.dc2.responsys.com dg05.server.wmq.host=jms1005-01-ri5.ri5.dc2.responsys.com;jms1005-02-ri5.ri5.dc2.responsys.com dg06.server.wmq.host=jms1006-01-ri5.ri5.dc2.responsys.com;jms1006-02-ri5.ri5.dc2.responsys.com dg07.server.wmq.host=jms1007-01-ri5.ri5.dc2.responsys.com;jms1007-02-ri5.ri5.dc2.responsys.com dg08.server.wmq.host=jms1008-01-ri5.ri5.dc2.responsys.com;jms1008-02-ri5.ri5.dc2.responsys.com dg09.server.wmq.host=jms1009-01-ri5.ri5.dc2.responsys.com;jms1009-02-ri5.ri5.dc2.responsys.com dg10.server.wmq.host=jms1010-01-ri5.ri5.dc2.responsys.com;jms1010-02-ri5.ri5.dc2.responsys.com dg11.server.wmq.host=jms1011-01-ri5.ri5.dc2.responsys.com;jms1011-02-ri5.ri5.dc2.responsys.com dg12.server.wmq.host=jms1012-01-ri5.ri5.dc2.responsys.com;jms1012-02-ri5.ri5.dc2.responsys.com dg13.server.wmq.host=jms1013-01-ri5.ri5.dc2.responsys.com;jms1013-02-ri5.ri5.dc2.responsys.com dg14.server.wmq.host=jms1014-01-ri5.ri5.dc2.responsys.com;jms1014-02-ri5.ri5.dc2.responsys.com dg15.server.wmq.host=jms1015-01-ri5.ri5.dc2.responsys.com;jms1015-02-ri5.ri5.dc2.responsys.com dg16.server.wmq.host=jms1001-01-ri5.ri5.dc2.responsys.com;jms1001-02-ri5.ri5.dc2.responsys.com dg17.server.wmq.host=jms1002-01-ri5.ri5.dc2.responsys.com;jms1002-02-ri5.ri5.dc2.responsys.com dg18.server.wmq.host=jms1003-01-ri5.ri5.dc2.responsys.com;jms1003-02-ri5.ri5.dc2.responsys.com dg19.server.wmq.host=jms1004-01-ri5.ri5.dc2.responsys.com;jms1004-02-ri5.ri5.dc2.responsys.com dg20.server.wmq.host=jms1005-01-ri5.ri5.dc2.responsys.com;jms1005-02-ri5.ri5.dc2.responsys.com dg21.server.wmq.host=jms1006-01-ri5.ri5.dc2.responsys.com;jms1006-02-ri5.ri5.dc2.responsys.com dg22.server.wmq.host=jms1007-01-ri5.ri5.dc2.responsys.com;jms1007-02-ri5.ri5.dc2.responsys.com dg23.server.wmq.host=jms1008-01-ri5.ri5.dc2.responsys.com;jms1008-02-ri5.ri5.dc2.responsys.com dg24.server.wmq.host=jms1009-01-ri5.ri5.dc2.responsys.com;jms1009-02-ri5.ri5.dc2.responsys.com dg25.server.wmq.host=jms1010-01-ri5.ri5.dc2.responsys.com;jms1010-02-ri5.ri5.dc2.responsys.com dg26.server.wmq.host=jms1011-01-ri5.ri5.dc2.responsys.com;jms1011-02-ri5.ri5.dc2.responsys.com dg27.server.wmq.host=jms1012-01-ri5.ri5.dc2.responsys.com;jms1012-02-ri5.ri5.dc2.responsys.com dg28.server.wmq.host=jms1013-01-ri5.ri5.dc2.responsys.com;jms1013-02-ri5.ri5.dc2.responsys.com dg29.server.wmq.host=jms1014-01-ri5.ri5.dc2.responsys.com;jms1014-02-ri5.ri5.dc2.responsys.com dg30.server.wmq.host=jms1015-01-ri5.ri5.dc2.responsys.com;jms1015-02-ri5.ri5.dc2.responsys.com dg31.server.wmq.host=jms1001-01-ri5.ri5.dc2.responsys.com;jms1001-02-ri5.ri5.dc2.responsys.com dg32.server.wmq.host=jms1002-01-ri5.ri5.dc2.responsys.com;jms1002-02-ri5.ri5.dc2.responsys.com dg33.server.wmq.host=jms1003-01-ri5.ri5.dc2.responsys.com;jms1003-02-ri5.ri5.dc2.responsys.com dg34.server.wmq.host=jms1004-01-ri5.ri5.dc2.responsys.com;jms1004-02-ri5.ri5.dc2.responsys.com dg35.server.wmq.host=jms1009-01-ri5.ri5.dc2.responsys.com;jms1009-02-ri5.ri5.dc2.responsys.com dg36.server.wmq.host=jms1010-01-ri5.ri5.dc2.responsys.com;jms1010-02-ri5.ri5.dc2.responsys.com dg37.server.wmq.host=jms1011-01-ri5.ri5.dc2.responsys.com;jms1011-02-ri5.ri5.dc2.responsys.com dg38.server.wmq.host=jms1012-01-ri5.ri5.dc2.responsys.com;jms1012-02-ri5.ri5.dc2.responsys.com dg39.server.wmq.host=jms1007-01-ri5.ri5.dc2.responsys.com;jms1007-02-ri5.ri5.dc2.responsys.com dg40.server.wmq.host=jms1008-01-ri5.ri5.dc2.responsys.com;jms1008-02-ri5.ri5.dc2.responsys.com
假设dg01.server.wmq.host=jms1001-01-ri5.ri5.dc2.responsys.com;jms1001-02-ri5.ri5.dc2.responsys.com是输入文件中的一行，并且您只对dg01.server.wmq.host=jms1001-01-ri5.ri5.dc2.responsys.com部分(直到但不包括分列)感兴趣，您可以通过运行
获得所需的输出:cat inputfile | awk -F ';' {'print $1'}
cut -d ';' -f1 inputfile
