tuckr:tldr:dd7f8

This is a command using the "tuckr" program, likely a command line tool or script.

The command is structured as follows:

• "tuckr" is the name of the program or script being executed.
• "add" is a sub-command or argument that specifies a certain action to be taken within the "tuckr" program.
• "*" represents a wildcard character that represents all files, directories, or entities. It is used to indicate that all items should be added.
• "-e" is another argument that is followed by a list of values.
• "${program1}" and "${program2}" are placeholders for variables that should be replaced with actual values.

Overall, this command is telling the "tuckr" program to add all files or entities using the wildcard "*", while specifying certain programs (program1 and program2) to be excluded ("-e" is typically used for exclusions or exceptions).

Note: Without further context or knowledge about the exact "tuckr" program, the specific behavior or purpose of this command cannot be determined.
