hallo, there is any shell command that compress and split a big sized file into many smaller compressed files for example a data file (file.data) with the size of 15 Mega bytes will compressed (by tar command for example) and divided to many smaller files of 3 mega each file (file.data1.zip, file.data2.zip .... ), because i have to email those files as attachments. PS: I would like that the zipped files will be recognized and gathered by windows too (like Win-rare tool).. thanks!! _________________________________________________________________ MSN® Calendar keeps you organized and takes the effort out of scheduling get-togethers. http://join.msn.com/?pgmarket=en-ca&page=byoa/prem&xAPID=1994&DI=1034&SU=http://hotmail.com/enca&HL=Market_MSNIS_Taglines Start enjoying all the benefits of MSN® Premium right now and get the first two months FREE*.
