I realize this has long since been answered with the grep solution, but for future generations I'd like to note that there are at least two other solutions for this particular situation, both of which are more efficient than grep. SOLUTION (provided by Rohit Jain with further input by beny23): grep -o '^*' text1.txt > text2.txt So for example: AA rough, cindery lava Īfter running grep -o '*' text1.txt > text2.txt, the line above becomes: AA The garbage text (that I want to remove) can contain anything, including spaces, special characters, etc. So I want to keep any/all characters up to and not including the blank space (removing everything from the blank space onward) in each line. The parts I want to keep include capital letters. Trying to piece together from different examples, but I have had no luck. I have tried numerous attempts such as: grep '*]' text1.txt > text2.txt So I was trying to use the grep command in Linux to keep only the characters in each line up to and not including the first blank space. My phone number is 666688888.I have a text file that has the following format: characters(that I want to keep) (space) characters(that I want to remove) My phone number is 666688888., and find all the numbers,, present in the string. In the following example, we will take a string, We live at 9-162 Malibeu. re.findall() returns list of strings that are matched with the regular expression. Where str is the string in which we need to find the numbers. + represents continuous digit sequences of any length. represents a regular expression to match a single digit in the string. To get the list of all numbers in a String, use the regular expression ‘+’ with re.findall() method.
