I had to make a few changes to get it to work:

My link url contained "/public.php" which had to be stripped by changing line 96 to
CLOUDURL="${2%/index.php/s/*}"

My use case is to push files with full path, which confused the upload, so I stripped the path to a "base" filename and then modified the send line to use it.

with nextcould 18 this script has started appending a (2) to each write of a file, which quickly gets problematic for operating systems without unlimited file/folder text length. I"m not sure why yet.

@MG2R @gessel
I have updated the original app with changes from you both.
Cheers! 🍺
Thanks

with nextcould 18 this script has started appending a (2) to each write of a file, which quickly gets problematic for operating systems without unlimited file/folder text length. I"m not sure why yet.

BTW, the (2) / (3) / etc happen when sending a file that already exists (it does not overwrite the file).

any way to change this behavior? The internal "versions" function is quite robust and has a lot of useful features. The (2)(2)(2) thing quickly breaks the file system.

Hi! This is an old fork of an old version of my script.
I have migrated it to a proper repository and made many changes since then.
https://github.com/tavinus/cloudsend.sh

The new version will overwrite the file by default.
It also has many other options, like using globs to send multiple files or renaming the target file.

Shares with passwords

Cloudsend v2 changed the way password parsing works.
Cloudsend 0.x.x used the -p parameter for the Environment password (changed to -e in v2+).
Please use EITHER -e OR -p, but not both. The last to be called will be used.

• Env Pass > Set the variable CLOUDSEND_PASSWORD='MySecretPass' and use the option -e
• Param Pass > Send the password as a parameter with -p <password>

Help info

$ ./cloudsend --help
Tavinus Cloud Sender v2.1.12

Parameters:
  -h | --help              Print this help and exits
  -q | --quiet             Disables verbose messages
  -V | --version           Prints version and exits
  -r | --rename <file.xxx> Change the destination file name
  -g | --glob              Disable input file checking to use curl globs
  -k | --insecure          Uses curl with -k option (https insecure)
  -p | --password <pass>   Uses <pass> as shared folder password
  -e | --envpass           Uses env var $CLOUDSEND_PASSWORD as share password
                           You can 'export CLOUDSEND_PASSWORD' at your system, or set it at the call
                           Please remeber to also call -e to use the password set

Use:
  ./cloudsend.sh [options] <filepath> <folderLink>
  CLOUDSEND_PASSWORD='MySecretPass' ./cloudsend.sh -e [options] <filepath> <folderLink>

Passwords:
  Cloudsend 2 changed the way password works
  Cloudsend 0.x.x used the '-p' parameter for the Environment password (changed to -e in v2+)
  Please use EITHER -e OR -p, but not both. The last to be called will be used

    Env Pass > Set the variable CLOUDSEND_PASSWORD='MySecretPass' and use the option '-e'
  Param Pass > Send the password as a parameter with '-p <password>'

Input Globbing:
  You can use input globbing (wildcards) by setting the -g option
  This will ignore input file checking and pass the glob to curl to be used
  You MUST NOT rename files when globbing, input file names will be used
  Glob examples: '{file1.txt,file2.txt,file3.txt}'
                 'img[1-100].png'

Send from stdin (pipe):
  You can send piped content by using - or . as the input file name (curl specs)
  You MUST set a destination file name to use stdin as input (-r <name>)

  Use the file name '-' (a single dash) to use stdin instead of a given file
  Alternately, the file name '.' (a single period) may be specified instead of '-' to use
  stdin in non-blocking mode to allow reading server output while stdin is being uploaded

Examples:
  CLOUDSEND_PASSWORD='MySecretPass' ./cloudsend.sh -e './myfile.txt' 'https://cloud.mydomain.net/s/fLDzToZF4MLvG28'
  ./cloudsend.sh './myfile.txt' 'https://cloud.mydomain.net/s/fLDzToZF4MLvG28'
  ./cloudsend.sh -r 'RenamedFile.txt' './myfile.txt' 'https://cloud.mydomain.net/s/fLDzToZF4MLvG28'
  ./cloudsend.sh -p 'MySecretPass' './myfile.txt' 'https://cloud.mydomain.net/s/fLDzToZF4MLvG28'
  ./cloudsend.sh -p 'MySecretPass' -r 'RenamedFile.txt' './myfile.txt' 'https://cloud.mydomain.net/s/fLDzToZF4MLvG28'
  ./cloudsend.sh -g -p 'MySecretPass' '{file1,file2,file3}' 'https://cloud.mydomain.net/s/fLDzToZF4MLvG28'
  cat file | ./cloudsend.sh - 'https://cloud.mydomain.net/s/fLDzToZF4MLvG28' -r destFileName

Send folder examples:
  find ./ -maxdepth 1 -type f -exec ./cloudsend.sh {} https://cloud.mydomain.tld/s/TxWdsNX2Ln3X5kxG -p yourPassword \;
  find /home/myname/myfolder -type f -exec ./cloudsend.sh {} https://cloud.mydomain.tld/s/TxWdsNX2Ln3X5kxG -p yourPassword \;
  tar cf - "$(pwd)" | gzip -9 -c | ./cloudsend.sh - 'https://cloud.mydomain.tld/s/TxWdsNX2Ln3X5kxG' -r myfolder.tar.gz
  tar cf - /home/myname/myfolder | gzip -9 -c | ./cloudsend.sh - 'https://cloud.mydomain.tld/s/TxWdsNX2Ln3X5kxG' -r myfolder.tar.gz
  zip -q -r -9 - /home/myname/myfolder | ./cloudsend.sh - 'https://cloud.mydomain.tld/s/TxWdsNX2Ln3X5kxG' -r myfolder.zip

Cool thanks! I'll jump over and work with the current one. Thank you for your code.
