. You can use the diff command to compare the contents of two directories: diff directory1 directory2 . The information given by the command tells you what to do to make the directories match. If there is no difference between the directories you are returned to the shell prompt . diff reports if a file or directory is only to be found in directory1 or directory2 . It also reports any line by line differences for files that are common to each directory. Example .

... Alfa_ang is a GUI for the rotang routine. The purpose of this routine is to calculate the optimum rotation angle for ALFA given the RA and Dec of a source and the date and time of the observation. The routine also returns the azimuth and zenith angle of the telescope at the requested time, thus it can be used to find the correct rotation angle and azimuth for the Fixed Azimuth Drift Scan observing mode used by the AGES drift precursor observation. ... To run alfa_ang at Arecibo: . ...
