Metadata Search via Grep

Attention : This code requires administrator privileges.

The macro parses an input string (format `Key^Value`), extracts the key, constructs the full path to a target metadata file, and uses an external macro `%AHGrpipe` to execute a case-insensitive `grep` command. The search result is stored in a macro variable and displayed in the log.

Data Analysis

Type : EXTERNAL

The code interacts with an external text file (defined by the `dir` and `metafile` parameters) via system commands, not via SAS libraries.

MACRO

Explanation :
Defines the `AHGshowmeta` macro. It parses the parameters, constructs the search command, and delegates execution to the `%AHGrpipe` macro. It depends on the global variable `&root3` and the `grep` system tool.
