grep:tldr:644a3
grep: Search for an exact string (disables regular expressions).
$ grep --fixed-strings "${exact_string}" ${filename}
try on your machine
The command you provided is used to search for a specific exact string in a given file using the grep
command with the --fixed-strings
option.
Here's a breakdown of the command:
grep
: It is a command-line utility used to search for patterns in files.--fixed-strings
: This option tellsgrep
to interpret the pattern as a fixed string rather than a regular expression. It treats the given search string as a literal string to match."${exact_string}"
: This is the variable that holds the exact string you want to search for. It is enclosed in double quotes to preserve any special characters or spaces contained within the string.${filename}
: This is the variable representing the name or path of the file you want to search within. It is usually replaced with the actual name or path of the file.
By combining these elements, the grep
command searches for the exact string stored in the ${exact_string}
variable within the specified ${filename}
file.
