I go with the trailing slash because: “If it ends with a slash, it’s a directory. If not, it’s a file.” is an easy convention to remember. At least on the operating systems I commonly use, doubling the slash causes no problems, while omitting the slash causes big ones. It is, therefore, safest to both … Read more
Starting from Eric’s answer, I included some improvements to make the code far more compact and reusable. Hope it’s useful. FileStream WaitForFile (string fullPath, FileMode mode, FileAccess access, FileShare share) { for (int numTries = 0; numTries < 10; numTries++) { FileStream fs = null; try { fs = new FileStream (fullPath, mode, access, share); … Read more
I’d probably recommend using something like rsync for this due to its include and exclude flags, e.g:- rsync -rav -e ssh –include ‘*/’ –include=”*.class” –exclude=”*” \ server:/usr/some/unknown/number/of/sub/folders/ \ /usr/project/backup/some/unknown/number/of/sub/folders/ Some other useful flags: -r for recursive -a for archive (mostly all files) -v for verbose output -e to specify ssh instead of the default (which … Read more
Make sure the file exists: use os.listdir() to see the list of files in the current working directory Make sure you’re in the directory you think you’re in with os.getcwd() (if you launch your code from an IDE, you may well be in a different directory) You can then either: Call os.chdir(dir), dir being the … Read more
For 3.1+, one of the following: isinstance(something, io.TextIOBase) isinstance(something, io.BufferedIOBase) isinstance(something, io.RawIOBase) isinstance(something, io.IOBase) For 2.x, “file-like object” is too vague a thing to check for, but the documentation for whatever function(s) you’re dealing with will hopefully tell you what they actually need; if not, read the code. As other answers point out, the first … Read more
Well, note that the request contains binary data, so I’m not posting the request as such – instead, I’ve converted every non-printable-ascii character into a dot (“.”).

Update April 27, 2015 Up and coming to the HTML5 scene is the download attribute. It’s supported in Firefox and Chrome, and soon to come to IE11. Depending on your needs, you could use it instead of an AJAX request (or using window.location) so long as the file you want to download is on the … Read more
Use path module in node.js returns the platform-specific file separator. example path.sep // on *nix evaluates to a string equal to “https://stackoverflow.com/” Edit: As per Sebas’s comment below, to use this, you need to add this at the top of your js file: const path = require(‘path’)
Under NT-style cmd.exe, you can loop through the lines of a text file with FOR /F %%i IN (file.txt) DO @echo %%i Type “help for” on the command prompt for more information. (don’t know if that works in whatever “DOS” you are using)
You have the noclobber option set. The error looks like it’s from csh, so you would do: cat /dev/null >! file If I’m wrong and you are using bash, you should do: cat /dev/null >| file in bash, you can also shorten that to: >| file
