You need to copy the files from your location to the destination ~pdslab/2015/assign7/cs15XX. Here cs15XX is your roll no. File names should follow the convention given in the assignment sheet. Remember to give read access rights on your source (program) files before uploading them. We assume that you have created a directory 'pdslab' in your account, under it you have created a directory for Assignment 7 named 'assign7', and have created the program files as per the given convention. Assuming the above mentioned structure, copy the final program files to the destination folder '~pdslab/2015/assign7/cs15XX' as follows: cp ~/pdslab/assign7/cs15XX-assign7-progY.c ~pdslab/2015/assign7/cs15XX/cs15XX-assign7-progY.c cp ~/pdslab/assign7/cs15XX-assign7-src-progY.c ~pdslab/2015/assign7/cs15XX/cs15XX-assign7-src-progY.c cp ~/pdslab/assign7/cs15XX-assign7-progY.h ~pdslab/2015/assign7/cs15XX/cs15XX-assign7-progY.h cp ~/pdslab/assign7/make15XX ~pdslab/2015/assign7/cs15XX/make15XX Here replace Y with the problem numbers. Use ls command to verify your submitted files: ls -l ~pdslab/2015/assign7/cs15XX/
