By following this procedure, you will be able to find out the number of occurrences of any given word of your choice in a text file very easily. The other approaches which are discussed are by using the grep command. This article was based on a very simple method for counting the total occurrences of a word within a text file in Linux Mint 21. The practice of counting lines in the file is usually adopted by the developers. s2.str.contains(.0, regexTrue) 0 True 1 True 2 False 3 True 4 False dtype: bool. The total number of occurrences of our specified word from the given text file is shown in the following image: Here, the “-o” flag is used to print only the matching words, the “-i” flag is used to ignore the case of the following word, “grep” represents the word whose occurrences are to be calculated, “grep.txt” is the name of the file in which we need to perform this operation whereas “wc –l” is used to count the number of lines in which the match is found. Now, we will use the command shown below to count the number of occurrences of the specified word: doc does not search all word files, you would use -include 'doc'. Step # 2: Use Grep to Count the Total Number of Occurrences of a Particular Word of the Target File From this file, we will be calculating the total occurrences of the word “grep” by using the grep command in Linux Mint 21. 22k 2 40 66 Possibly better with GNU grep: printf d Asian Femalesn (grep -Pc ,sAsians,sFemales filename. When the -c or -count option is also used, grep does not output a count. To count the number of lines that a string appears in using grep: grep -c string. The target text file is shown in the following image. When grep stops after NUM matching lines, it outputs any trailing context lines. To display the contents of that file, we will execute the command shown below: The syntax is: grep -c string filename grep -c foo bar. For example, to count the occurrences of both the values 5 and 7, we would use the following command: grep -c 57 filename. If you want to find the total number of occurrences of any given word in a text file in Linux Mint 21 with the help of the grep command, then you should perform the following steps: Step # 1: View the Target Fileįirst, we will show you the target file in which we will be counting the occurrences of a particular word. When grep is combined with regex ( reg ular ex pressions), advanced searching and output filtering become simple. This guide will walk you through the complete procedure of counting the total number of occurrences of a word within a text file in Linux Mint 21.” Using the Grep Command to Count the Occurrences of a Word in a Text File in Linux Mint 21 Introduction The grep command (short for G lobal R egular E xpressions P rint) is a powerful text processing tool for searching through files and directories. at 17:57 2 GauthamHonnavara grep :0 looks for line that match the string :0. The Story Behind grep The grep command is famous in Linux and Unix circles for three reasons. It also works with piped output from other commands. Using the -o option tells grep to output each match on. Plain grep -c on the data will count the number of lines that match, not the total number of words that match. One of the purposes for which this command can be used is to count the total occurrences of a specific word within a file. The Linux grep command is a string and pattern matching utility that displays matching lines from multiple files. Given such a requirement, I would use a GNU grep (for the -o option ), then pass it through wc to count the total number of occurrences: grep -o -i iphone TweetData wc -l 3. For the answer from loki-astari, the following error is reported: awk -F" '' mis.“Grep is a very useful Linux command that can perform a variety of different operations. This is safe (it handles hidden files, paths containing spaces, dashes and even newlines) and POSIX compatible: find /path/to/directory -mindepth 1 -type f -name '. The answers using awk fail if the number of matches is too large (which happens to be my situation). 10 Answers Sorted by: 60 Unfortunately this benign problem is difficult to solve in a way which supports all file names and is portable.
