You missed the most important, biggest difference between them: glob gives you back a list, but opendir gives you a directory handle. You can pass that directory handle around to let other objects or subroutines use it. With the directory handle, the subroutine or object doesn’t have to know anything about where it came from, … Read more
Glob patterns support character ranges: glob(‘my/dir/*.[cC][sS][vV]’)
If you use bash and have the extglob shell option set (which is usually the case): mv ~/Linux/Old/!(Tux.png) ~/Linux/New/
You’re most likely seeing a special feature of some shells that allow wildcard filename patterns to match across directory boundaries, as opposed to a single *, which is a wildcard that matches only within a directory. If you do not have such a shell, ** will likely be equivalent to *, because “matching zero or … Read more
The extended glob syntax you are trying to use is turned off by default; you have to enable it separately in each script where you want to use it. shopt -s extglob Scripts should not use ls though I imagine you were using it merely as a placeholder here.
I suggest use list comprehension with concat: import glob import pandas as pd files = glob.glob(“TransactionData\Promorelevant*.csv”) dfs = [pd.read_csv(f, header=None, sep=”;”) for f in files] salesdata = pd.concat(dfs,ignore_index=True)
import glob import shutil dest_dir = “C:/test” for file in glob.glob(r’C:/*.txt’): print(file) shutil.copy(file, dest_dir)
When you pass in an array of full paths, each file is processed independently. The globbing doesn’t know where the root of the path is (in fact, it guesses based on the first glob). Therefore, each file is rooted in the folder it contains, and the relative path is empty. However, there is an easy … Read more
I like my code a little more semantic, so I wrote this extension method: using System.Text.RegularExpressions; namespace Whatever { public static class StringExtensions { /// <summary> /// Compares the string against a given pattern. /// </summary> /// <param name=”str”>The string.</param> /// <param name=”pattern”>The pattern to match, where “*” means any sequence of characters, and “?” … Read more
You can use git add [path]/\*.java to add java files from subdirectories, e.g. git add ./\*.java for current directory. From git add documentation: Adds content from all *.txt files under Documentation directory and its subdirectories: $ git add Documentation/\*.txt Note that the asterisk * is quoted from the shell in this example; this lets the … Read more
