问题 I'm trying to write a perl script which takes the output of colorgcc (or any other script that prints colored text to terminal), adds/removes parts of the string, and then prints the result in the same color as the input string.

问题 Running this statement in OS X Terminal for i in `ls -v *.mkv`; do echo $i; done will successfully print out all the file names in the directory in name order with each file name on its own line. Source: This StackOverFlow answer However, if I run this statement in OS X Terminal for i in 'ls -v *.mkv'; do echo $i; done the output is "ls -v fileName1.mkv fileName2.mkv", etc. with all the file names concatenated into one long line (as opposed to each being printed on its own line).

问题 How can I clone an existing Parse Cloud Project files to my computer with the command line tool? I tried parse new and selected a project but it created a folder with new files, not the files that I already had in the Parse Cloud.
