Hello ,
Thanks a lot for your time. To add to my post, my a_copy.txt is something like this:
sjdsajdsd kjfksls'fsaf sandlksadnksalndop djsndsan;sa sdsakdslkdsa sakdsakdsa ..................... ................. NAME|VALUE = a ksadksad dewidewjrw djsdnsalkd dskdsa;dkjsa .................... ............................. TASK|VALUE = copy dsakdmsald;sadsa dsalkdsldk'dls ................................ dskmdsldsdsda CAPS|VALUE = 34 dksdmlsajdsajdsa .............................. dsdksld;sads PKG_TYPE|VALUE = minimal dsmds.dsa.d lsdksadjsldjsdjpos ........................... ............................ .................................. jndlkjsandlksandsndsa jdnsakjdnkjs;dsa kdjslkdjsa;lkds STACK|VALUE = 4 dfdskjff;sdf ............................. ........................ SHIP|VALUE = junk kdskdsakjdl'sa jdsajd;lksahdsakda .......................... dsjads .........................
And input file is user based, so its not confined to only the content you see in my example. It can have multiple values under "NAME|VALUE =" and "TASK|VALUE =" . I have to read these two keywords from the input file, and open the correct (NAME|VALUE)_(TASK|VALUE).txt. In my example, the first one happens to be "a_copy.txt". Second one happens to be "z_cut.test" and third one is "c_paste.txt". There can be many more like this based on the user input. So, I have to grep for the lines that follow "NAME|VALUE = a" and "TASK|VALUE = copy" in the input file, and replace those lines in the .txt file For example, in this case, a_copy.txt, I have to replace the lines "CAPS|VALUE = 34" with "CAPS|VALUE = 0" and "PKG_TYPE|VALUE = minimal" with "PKG_TYPE|VALUE = premium". In the c_paste.txt I have to replace "STACK|VALUE = 65" with "STACK|VALUE = 2" and "SHIP|VALUE = medium" with "SHIP|VALUE = lowtier" and so on. And you are right, since z_cut.txt file doesnt exist, the code has to throw an error in the end giving a list of all the non existent files and exit. The exit should happen only after the code has successfully run on the existing files. For example, post processing , a_copy.txt should look like:
sjdsajdsd kjfksls'fsaf sandlksadnksalndop djsndsan;sa sdsakdslkdsa sakdsakdsa ..................... ................. NAME|VALUE = a ksadksad dewidewjrw djsdnsalkd dskdsa;dkjsa .................... .............................
