bash loop through files in directory recursively

This is done to find both visible and hidden directories within the present working directory, excluding the root directory: to just loop through directories: find -path './*' -prune -type d to include symlinks in the result: find -L -path './*' -prune -type d to do something to each directory (excluding symlinks): This output goes to the original_filenames.txt file in the directory. If this condition returns true, we simply output the value of file using the echo command. For example, to list the files in the C:\PS directory, run the command: ...

DOS Batch is the Windows equivalent of shell scripting and can be used to perform all sorts of different actions. The Get-ChildItem cmdlet displays a list of child (nested) objects on a specified drive or directory. find -type d -name "TC_*" | sort That's what I have so far... it finds the appropriate directories and then sorts them. To filter all files with a specific file extension, you’d have to extract the extension from the filename which is just a character array. 3. To create a bat file just make a file and give it the extension "bat". The body of the loop outputs the name of the directory, and then a list of all files and directories, recursively, in that directory. Windows is not a POSIX system, but dirent is available in MinGW or Cygwin implementations. This is the most popular file system cmdlet. Example. Create an automated script that will check for Uploads in a specified Directory and move them to another specified Directory if the files are completely uploaded. (1) ls writes one file per line (what the -1 option specifies) by default when the standard output is a pipe (so it’s superfluous in your answers). Example below, with the caveat that I used a non-working "curl" command!
