Unhash / Alias Unfunction Unhash
Alias Unfunction Unhash
Reverts shell function definitions back to their original command state.
unhash -f unhash -f #!/bin/bash
# Alias Unfunction Unhash
unhash -f import subprocess
# Alias Unfunction Unhash
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"unhash",
"-f"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: unhash not found. Please install it first.")
if __name__ == "__main__":
run_command() When To Use
When a shell function has overridden a command, and the original functionality is needed for script execution or manual command use.
Pro Tip
Use `type <function_name>` to verify if a function is currently defined before unhashing.
Warning
Destructive operation. Confirm the target path and keep a backup before executing.
Anatomy of Output
Understanding the result
unhash -f Unhash Command Initiates reverting the recent hash or function.
Function f overridden by command /bin/command-name Unhash Action Log Detailing which function is reverted.
Unhashing complete: reverted to original command Completion Notification Indicates that the original command is now active.
Power User Variants
Optimized versions
unhash -v Verbose version of unhash to see detailed operations.
unhash -a Unhash all functions at once.
Troubleshooting
Common pitfalls
unhash: command not found
Solution: Ensure the command exists in the path; check using `which command-name`.
unhash: no function defined
Solution: Verify that a function is currently overriding it.
unhash: unable to remove non-functional definitions
Solution: Check for syntax errors in the function definitions.
