awk to print the first column. The first column of any file can be printed by using $1 variable in awk. But if the value of the first column contains multiple words then only the first word of the first column prints. By using a specific delimiter, the first column can be printed properly.
The grep command searches through the file, looking for matches to the pattern specified. To use it type grep , then the pattern we're searching for and finally the name of the file (or files) we're searching in.
The `awk` command can be applied in different ways to get the first column and/or last column from any command output or from tabular data. It is important to note that a field separator is required in the command, and if one is not provided, then the space is used.
Use awk. cat myfile | awk '{print $1}' | grep query
