find: Run a command for each file (use `{}` within the command to access the filename).
$ find ${root_path} -name '${*-ext}' -exec ${wc -l {} }\;

This command is used to find all files in the directory specified by the variable "root_path" that have a certain extension, and then count the number of lines in each found file using the "wc" command.
Let's break down the individual components of the command:
find
: The basic Unix command to search for files and directories.${root_path}
: It is a variable that should have been previously defined and holds the path of the directory where the search will be performed.-name
: This option is used to specify the name, or a pattern of the filename, to match during the search. In this case, it uses the pattern '${*-ext}' which can be interpreted as searching for files with any prefix followed by '-ext' as the extension.-exec
: This option is used to execute a command on each file that matches the search criteria.${wc -l {} }
: It is likely that there is an error in this part of the command. It seems to be intended to use thewc
command to count the number of lines in each found file. However, there are syntax issues. The correct form of the command would bewc -l {} \;
.wc
is the command used to count lines,-l
is the option for line counting,{}
represents the placeholder for the file name found by thefind
command, and\;
terminates the-exec
option for each file that matches.
So, the corrected command would be: find ${root_path} -name '${*-ext}' -exec wc -l {} \;
, which will search for files with a specific extension and then count the number of lines in each one.
This explanation was created by an AI. In most cases those are correct. But please always be careful and
never run a command you are not sure if it is safe.
