![]() So just don’t try to handle those as though they are words, and there is no problem. Also note that this breaks on longer, comma-separated numbers, turning each group into a (probably meaningless) lone 1-, 2-, or 3-digit number. Note the apostrophe in the first set given to tr such that possessives and contractions remain whole words but parenthesis, quotation marks, and other punctuation are stripped off. The final sort is optional, used to list the words by frequency of appearance instead of alphanumerically. grep is used to remove blank lines only because if you don’t, uniq prints out the number of blank lines as well, and I didn’t yet come up with a better way to do that. Similarly, in the command grep 'John' < Phones, the grep command reads its input from the Phones file in the current directory, not from the keyboard. Then uniq -c deduplicates them as well as printing the number of occurrences. While grep -c works on a line, this puts every word or number on its own line and sorts them. Tr -c "'" "\n" | grep "]" | sort | uniq -c | sort -n ![]() It’s not perfect but I adapted the ‘ tr‘ approach to print a count of each word in some standard input: This is how the total number of matching words is deduced. The -o option is what tells grep to output each match in a unique line and then wc -l tells wc to count the number of lines. Using grep -c alone will count the number of lines that contain the matching word instead of the number of total matches. ![]() You can use grep command to count the number of times "mauris" appears in the file as shown. Nibh ante cursus purus, vel sagittis velit mauris vel metus enean fermentum risus. Mauris suscipit, ligula sit amet pharetra semper, Suppose you have an example.txt file containing the sentences: Praesent in mauris eu tortor porttitor accumsan. and finding the occurrence of words or phrases are as easy as hitting Ctrl + F and typing in the characters you want to search for.Ī GUI does make everything easy but what happens when you can only work from the command line and you want to check the number of times a word, phrase, or character occurs in a text file? It’s almost as easy as it is when using a GUI as long as you’ve got the right command and I’m about to narrate to you how it is done. Graphical User Interface word processors and note-taking applications have information or detail indicators for document details such as the count of pages, words, and characters, a headings list in word processors, a table of content in some markdown editors, etc. ![]()
