This is because the content of file is not being copied. Using -f option will force the copying activity. If the destination files cannot be opened, then -f will try again. To do this, we can use --remove-destination option. This option is contrast with -f option above.
If the cp command find the same file name on the destination folder, cp command will remove destination file first, the copy the new one. Cp command is one of the basic Linux commands. For those who want to learn Linux, must know this command. Of course, you can type man cp or cp --help from your console to display its manual page to explore more detail. Here are some samples of cp command that might useful in day-to-day operation 1 cp command This is a very basic cp usage.

Rebooting is not necessary after running the export command on Linux and macOS. Please see the section about OS-specific file types in gsutil help rsync. While that section refers to the rsync command, analogous points apply to the cp command. Copy all source versions from a source bucket or folder.
If not set, only the live version of each source object is copied. If an error occurs, continue attempting to copy the remaining files. If any copies are unsuccessful, gsutil's exit status is non-zero, even if this flag is set. This option is implicitly set when running gsutil -m cp Copy in "daisy chain" mode, which means copying between two buckets by first downloading to the machine where gsutil is run, then uploading to the destination bucket.
The default mode is a "copy in the cloud," where data is copied between two buckets without uploading or downloading. During a "copy in the cloud," a source composite object remains composite at its destination. However, you can use "daisy chain" mode to change a composite object into a non-composite object.
Use stdin to specify a list of files or objects to copy. You can use gsutil in a pipeline to upload or download objects as generated by a program. Applies gzip transport encoding to any file upload whose extension matches the -j extension list.
This is useful when uploading files with compressible content such as. This also saves network bandwidth while leaving the data uncompressed in Cloud Storage. When you specify the -j option, files being uploaded are compressed in-memory and on-the-wire only. Both the local files and Cloud Storage objects remain uncompressed.
The uploaded objects retain the Content-Type and name of the original files. You can change this compression buffer size to a higher limit. Applies gzip transport encoding to file uploads. This option works like the -j option described above, but it applies to all uploaded files, regardless of extension. Outputs a manifest log file with detailed information about each item that was copied. This manifest contains the following information for each item:.
If the log file already exists, gsutil uses the file as an input to the copy process, and appends log items to the existing file. Objects that are marked in the existing log file as having been successfully copied or skipped are ignored.
Objects without entries are copied and ones previously marked as unsuccessful are retried. This option can be used in conjunction with the -c option to build a script that copies a large number of objects reliably, using a bash script like the following:.
The -c option enables copying to continue after failures occur, and the -L option allows gsutil to pick up where it left off without duplicating work. The loop continues running as long as gsutil exits with a non-zero status. A non-zero status indicates there was at least one failure during the copy operation. Preserves ACLs when copying in the cloud. You can mitigate this performance issue using gsutil -m cp to perform parallel copying.
If you want all objects in the destination bucket to end up with the same ACL, you can avoid these performance issues by setting a default object ACL on that bucket instead of using cp -p. See gsutil help defacl. Note that it's not valid to specify both the -a and -p options together. These fields are the user ID of the owner, the group ID of the owning group, the mode or permissions of the file, and the access and modification time of the file.
For downloads, these attributes are only set if the source objects were uploaded with this flag enabled. On Windows, this flag only sets and restores access time and modification time. Applies gzip content-encoding to any file upload whose extension matches the -z extension list. This can both improve performance and reduce costs. When you specify the -z option, the data from your files is compressed before it is uploaded, but your actual files are left uncompressed on the local disk.
The uploaded objects retain the Content-Type and name of the original files, but have their Content-Encoding metadata set to gzip to indicate that the object data stored are compressed on the Cloud Storage servers and have their Cache-Control metadata set to no-transform. Note that if you download an object with Content-Encoding:gzip , gsutil decompresses the content before writing the local file.
Applies gzip content-encoding to file uploads. This option works like the -z option described above, but it applies to all uploaded files, regardless of extension.
