To get the count of a specific keyword or a term from the contents of a file, we can use the
cat command followed by the
path to the file, then the
| operator (aka pipe operator), then the
grep command, then the keyword you want to search for and finally the
-c flag (count flag) in the Linux terminal.
# Get the count of a specific # word from the contents of a file cat <PATH_TO_FILE> | grep <YOUR_SEARCH_TERM> -c
For example, let's say we have a file called
myFile.txt which has some content like below,
Wikipedia is a free content, multilingual online encyclopedia written and maintained by a community of volunteer contributors through a model of open collaboration, using a wiki-based editing system. Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger; Sanger coined its name as a blending of "wiki" and "encyclopedia". Initially available only in English, versions in other languages were quickly developed. Its combined editions comprise more than 57 million articles, attracting around 2 billion unique device visits per month, and more than 17 million edits per month (1.9 edits per second).
Now, we want to find the number of times a specific word occurred or count of the word
Wikipedia from the contents of the
myFile.txt file. We can do that using the
grep commands like this,
# Get the count of a specific # word from the contents of a file cat myFile.txt | grep Wikipedia -c
The output of running the above command may look like this,
As you can see that the word
Wikipedia has a count of
2 in the above output.
See the execution of the above command live in repl.it.
That's all 😃!
