tsv-filter:tldr:00730

The command you provided is using a tool called "tsv-filter" to filter a TSV (tab-separated values) file based on a specific condition and count the number of matching rows.

Here is a breakdown of the command:

• tsv-filter: This is the name of the tool or command-line program being executed.
• --count: This option instructs the tool to count the number of rows that meet the filtering condition.
• -H: This option tells the tool to consider the first row in the TSV file as the header row and ignore it during filtering.
• --eq: This option specifies that the filtering condition will be based on an equality comparison.
• ${field_name}:${number}: This is the condition used for filtering. It consists of two parts separated by a colon. ${field_name} should be replaced with the name of the specific field (column) in the TSV file you want to apply the filter on. ${number} should be replaced with the specific value you want to filter on within that field.
• ${path-to-tsv_file}: This is the path or location of the TSV file on your system that you want to filter.

To summarize, the command is filtering a TSV file by checking if the value in a specific field (${field_name}) is equal to a certain number (${number}). The tool will then count the number of rows that meet this condition, excluding the header row.
