However all modern versions of grep have this built-in. Running a single command/process is more efficient, and so with large files will be noticably faster:
grepkeyword file.txt output.txt
grep can also display an entire file, (like cat), by using the grep keyword '.' which will match lines with at least 1 character. Alternatively the grep keyword '^' will match the beginning of every line including blank lines.
When grep is used to display multiple files, it will prepend each line of output with the filename:
$ grep . *.txt
Examples:
Display a file:
$ cat myfile.txt
Display all .txt files:
$ cat *.txt
Concatenate two files:
$ cat File1.txt File2.txt > union.txt
If you need to combine two files but also eliminate duplicates, this can be done with sort unique:
$ sort -u File1.txt File2.txt > unique_union.txt
Put the contents of a file into a variable
$ my_variable=`cat File3.txt`
