Gcrane / Set Maximum Number Of Concurrent Copies
Set Maximum Number Of Concurrent Copies
Configures the maximum number of jobs for concurrent image copying operations.
gcrane copy <source> <target> -j <nr_of_copies> gcrane copy <source> <target> -j <nr_of_copies> #!/bin/bash
# Set Maximum Number Of Concurrent Copies
gcrane copy {{source}} {{target}} {{[-j|--jobs]}} {{nr_of_copies}} import subprocess
# Set Maximum Number Of Concurrent Copies
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"gcrane",
"copy",
"<source>",
"<target>",
"-j",
"<nr_of_copies>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: gcrane not found. Please install it first.")

run_command() When To Use
When managing a large number of images to ensure system resources are optimized during copy operations.
Pro Tip
Monitor system load before setting high numbers for the -j parameter; overloading may degrade performance.
Command Builder
Tune the command before you copy it
gcrane copy <source> <target> -j <nr_of_copies> Anatomy of Output
Understanding the result
Setting maximum concurrent jobs to: 4 Concurrent Job Limit Indicates the number of parallel jobs being set.
Starting copy operations: source-image-path to target-image-path with 4 jobs. Copy Operation Confirms the initiation of copying process.
Copy completed for 4 images. Completion Status Indicates that operations completed successfully.
Troubleshooting
Common pitfalls
ERROR: Invalid number of jobs specified.
Solution: Ensure that the number of jobs is a positive integer.
ERROR: Unable to start copy process due to insufficient resources.
Solution: Check system resource availability before running high job concurrency.
ERROR: Copy operation failed for source-image-path
Solution: Verify that the source path is valid and accessible.
