EXAMPLES OF THE ADD COMMAND 'LZX a myarchive.lzx testfile.txt' would add the file 'testfile.txt' to the archive 'myarchive.lzx'. However, if 'testfile.txt' were already present in the archive, then it would not be added. If 'myarchive.lzx' didn't exist at the time the command was invoked, then 'myarchive.lzx' would be created as a new archive. 'LZX a myarchive newfile.txt' would perform exactly the same operation as the above, since LZX would automatically append the '.lzx' extension onto the archive name 'myarchive'. To alter this behavior, the -X option can be used. 'LZX a myarchive *.txt *.doc test.tmp' would add to the archive 'myarchive.lzx' all files ending in '.txt', '.doc', and the file 'test.tmp'. 'LZX a myarchive.lzx subdir/newfile.txt' would add the file 'subdir/newfile.txt' to the archive 'myarchive.lzx'. The file would be stored as 'newfile.txt' within the archive; that is, the 'subdir/' prefix would not be preserved. In order to have the file stored as 'subdir/newfile.txt' within the archive, the -x option would be required: 'LZX -x a myarchive.lzx subdir/newfile.txt'
