Test All Ppd Files In Directory

Recursively searches for PPD files in a directory and tests them for correctness using cupstestppd.

Terminal

find . -name \\*.ppd \\! -execdir cupstestppd -q '{}' \\; -print

find . -name //*.ppd //! -execdir cupstestppd -q "{}" //; -print

#!/bin/bash

# Test All Ppd Files In Directory
find . -name \\*.ppd \\! -execdir cupstestppd -q '{}' \\; -print

import subprocess

# Test All Ppd Files In Directory
# Make sure to replace <placeholders> with actual values
def run_command():
    cmd = [
        "find",
        ".",
        "-name",
        "\\\\*.ppd",
        "\\\\!",
        "-execdir",
        "cupstestppd",
        "-q",
        "'{}'",
        "\\\\;",
        "-print"
    ]
    
    try:
        print(f"Executing: {' '.join(cmd)}")
        subprocess.run(cmd, check=True)
    except subprocess.CalledProcessError as e:
        print(f"Error: {e}")
    except FileNotFoundError:
        print("Error: find not found. Please install it first.")

if __name__ == "__main__":
    run_command()

When To Use

During printer setup or troubleshooting to ensure all PPD files function correctly.

Pro Tip

Run from a user account that has permission to the printer configuration settings, or tests may fail due to permission denial.

Anatomy of Output

Understanding the result

Testing PPD files in directory: . Scanning Directory

Indicates the current directory being scanned for PPD files.

PPD file: printer.ppd tested successfully: OK Test Result

Reports success or failure of individual PPD file tests.

Total PPD files tested: 10, Errors: 0 Summary Result

Gives a total count of PPD files examined and any errors found.

Troubleshooting

Common pitfalls

No PPD files found in the specified directory.

Solution: Ensure that PPD files are present in the directory before testing.

Invalid argument: cupstestppd -q: extra condition not allowed

Solution: Review and adjust syntax; remove unintended constraints.

Permission denied: unable to access printer configuration.

Solution: Run test command as a user with appropriate permissions.
