You could use cut on one file to seperate each field to a seperate file, then use paste to put it back together with the right seperator. After that sort both files and the run a diff, grepping for only deleted lines of one file: man cut man paste man sort man diff man grep $ cat xx.dat me,20,aax you,32,fds them,12,wsx $ cat yy.unl us|45|wrt me|20|aax them|12|wsx $ cut -d'|' -f1 yy.unl > field1 $ cut -d'|' -f2 yy.unl > field2 $ cut -d'|' -f3 yy.unl > field3 $ paste -d, field1 field2 field3 | sort > tmp $ cat xx.dat | sort | diff - tmp | grep '^<' | cut -d' ' -f2 > db2 $ cat db2 you|32|fds $ diff xx.dat db2 | grep '^<' | cut -d' ' -f2 > new-xx.dat $ mv new-xx.dat xx.dat $ cat xx.dat me,20,aax them,12,wsx But perhaps sed, awk or perl would be better. > > > > Thanks > > > > Jemima > > > > > > > ----------------------------------------- > This message and its contents (to include attachments) are the property of > Kmart Corporation (Kmart) and may contain confidential and proprietary > information.
