This article will explain how to use findthe command to locate any text in a file -execusing the -p parameter of the command.find

Searching for files in Bash using findcommand

findCommand is a useful tool to search and select files in bash. We use findcommand with some expressions and actions.

example:

find ./folder -name *.txt

We use the command with a search location find, such as ./folderfor foldera directory and its subdirectories. -name *.txtThe expression is to find every file in that location .txt.

Searching for Files in Bash Using -exec-r Options and -r Commandsfind

We can use -execthe -f command action to run commands on files found findusing the -f command.find

example:

find ./folder -name *.txt -exec file {} +

Output:

./folder/hello.txt: ASCII text, with no line terminators

-execRun filethe command and display findthe file type returned by the command.

find -execSearch for specific text in Bash using command

We can use the command with -execthe -p option findto find files that contain the text we are searching for.

The main concept is to use findthe command to get each file in the working directory and execute grepthe command to find the text in each file.

example:

# !/bin/bash
find . -exec grep linux {} \;

The following command will return textthe line where the specified is found.

Output:

find . -exec grep linux {} \;
find . -exec grep linux {} +
title = "Unzip .gz file in linux"
description = "How to unzip a .gz file in linux"

To prevent the shell from interpreting ;the delimiter, we use before it \. Using this strategy, we only get the lines where text was detected.

;We can get the line and the file name where it is found by replacing the separator with +.

# !/bin/bash
find . -exec grep linux {} +

Output:

./bash.sh:find . -exec grep linux {} \;
./bash.sh:find . -exec grep linux {} +
./unzip_gz_linux.txt:title = "Unzip .gz file in linux"
./unzip_gz_linux.txt:description = "How to unzip a .gz file in linux"

findThe way the expression results are processed is determined by the separator. If we use a semicolon ;, -execthe command will repeat each result independently.

If we use +the notation, the results of all expressions will be concatenated and fed to -execthe command, which is run only once. For performance reasons, we prefer to use +the delimiter.
