in tcsh terminal i have the following line of code cat fileName.txt | grep "a"
which extracts all the instances of "a" from the file in the terminal.. however when i am trying to create a txt while, i am unable to do so for some reason..this is the syntaxt i am using -- cat fileName.txt | frep "a" > a.txt file then appears in the folder, however, it can no be opened because "the file is not in the right format".. does anybody know how to correct this problem? thanks so much -- http://mail.python.org/mailman/listinfo/python-list
