c - Unable to run compiled files - bash: ./a.out: Permission denied. (I've tried chmod) -


i've compiled c source using cc test.c, , did generate a.out file.

however when run error - 

bash: ./a.out: permission denied

my source not in home directory, on different fat-32 partition, i've mounted drive in code using following command - 

$ udisks --mount /dev/sda7 --mount-options umask=022 mounted /org/freedesktop/udisks/devices/sda7 @ /media/48e9-fd53 $ cd /media/48e9-fd53/c

then compile code using cc

i've tried gcc. still same error.

then did - chmod +x a.out, still same problem. with(chmod 755 a.out) , chmod u+x a.out.

i've tried compiling , executing program using sudo.

i've tried - sudo chown sannidhya:sannidhya a.out.

i've tried every thing found after googling, still couldn't work.

how can run .out file (without moving home directory)?

note - using ubuntu 12.04 lts.

but weird thing here is, after running chmod +x a.out, on running - ls -l a.out, get-

-rw-r--r-- 1

also when check properties of a.out, under permissions tab, when check allow executing file program,the tick appears , disappears.

seems you've mounted partition with no-exec flag set. you'll have remount partition:

sudo mount -o remount -o exec /dev/sda7

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
