Hello,

I just want to share this. If you consider my function as an worthy example for the homepage, go for it!:

transfer()
{
    local file="${1}"
    local filename="${file##*/}"
    # show delete link from the response header after upload. the command "sed" is necessary to clean up the output, "gsub()" in "awk" does not work.
    curl --request PUT --progress-bar --dump-header - --upload-file "${file}" "https://transfer.sh/${filename}" | sed "s/#//g" | awk '/x-url-delete/ { print "Delete command: curl --request DELETE " $2 } END{ print "Download link: " $1 }'
}

Example outputs:

$ transfer image.img

Delete command: curl --request DELETE https://transfer.sh/Ge9cuW/image.img/<some_delete_token>

I just tested this on my end and it works for zsh and bash.

What output do you get, if you upload a small file via curl like the following?:

$ echo "some_content" > "deleteme"
$ curl --request PUT --progress-bar --dump-header - --upload-file "deleteme" "https://transfer.sh/deleteme"

curl returns me this:

Maybe the key x-url-delete is written differently and not matched by gawk.

These are the package versions I am using and an upload test, which I did in bash:

I found the issue!

It seems, that x-url-delete is written differently in some versions of curl as seen in the README.md file.

Since there are different versions of awk like gawk, mawk and so on, I am going to match x-url-delete without case sensitivity; using the variable IGNORECASE only works for gawk and is not sufficient.

This function should work now:

## upload files to "transfer.sh"
transfer()
{
    local file="${1}"
    if [[ ! -f "${file}" ]]
    then
        echo -e "\e[01;31mCould not find file: '${file}'.\e[0m" >&2
        return 1
    else
        local filename="${file##*/}"
        # show delete link from the response header after upload. the command "sed" is necessary to clean up the output, "gsub()" in "awk" does not work.
        curl --request PUT --progress-bar --dump-header - --upload-file "${file}" "https://transfer.sh/${filename}" \
            | sed "s/#//g" \
            | awk 'tolower($0) ~ /x-url-delete/ { print "Delete command: curl --request DELETE " $2 } END{ print "Download link: " $1 }'
    fi
}

nice @keks24 , thanks for sharing

I will add to README.md for the moment, since the frontend is already cluttered with examples unluckily :(

if you are able to write a cross-shell (bash/zsh at least) version of your function, including echoing delete command (that's really great!) we could promote it to frontend.

please let me know what do you think

I could not help myself, but to improve the function once again. It is slowly growing, where I almost got to the point to create a separate repository for it, but I will keep it like this for now.

I consider this the final version now.

It can now upload multiple files, shows the size of each file in Kibibyte and prompts before uploading:

$ transfer --help
transfer - Upload arbitrary files to "transfer.sh".

Usage: transfer [options] [<file>]...

OPTIONS:
  -h, --help
      show this message

EXAMPLES:
  Upload a single file from the current working directory:
      transfer "image.img"

  Upload multiple files from the current working directory:
      transfer "image.img" "image2.img"

  Upload a file from a different directory:
      transfer "/tmp/some_file"

  Upload all files from the current working directory. Be aware of the webserver's rate limiting!:
      transfer *

  Upload a single file from the current working directory and filter out the delete command:
      transfer "image.img" | awk --field-separator="Delete command:" '/Delete command:/ { print $2 }'

  Show help text from "transfer.sh":
      curl --request GET "https://transfer.sh"

## upload files to "transfer.sh"
transfer()

It is slowly growing, where I almost got to the point to create a separate repository for it, but I will keep it like this for now. I consider this the final version now.

I think, that has something to do with --progress-bar, which is not perfectly removed by sed.

Does this one with --silent and --show-error without sed work for you?:

$ curl --request PUT --silent --show-error --dump-header - --upload-file "image.img" "https://transfer.sh/image.img" | awk 'tolower($0) ~ /x-url-delete/ { print "Delete command: curl --request DELETE " $2 } END{ print "Download link: " $1 }'

Leaving out the parameter --silent messes up the output for some reason:

$ curl --request PUT --dump-header - --upload-file "image.img" "https://transfer.sh/image.img" | awk 'tolower($0) ~ /x-url-delete/ { print "Delete command: curl --request DELETE " $2 } END{ print "Download link: " $1 }'

This one should be the final, functioning version for zsh and bash, which also filters out the deletion token:

        # show delete link and filter out the delete token from the response header after upload.
        # it is important to save "curl's" "stdout" via a subshell to a variable or redirect it to another command,
        # which just redirects to "stdout" in order to have a sane output afterwards.

        # redirecting "curl's" "stderr" to "stdout" ("2>&1") will hide the progress bar.
        local curl_output=$(curl --request PUT --progress-bar --dump-header - --upload-file "${file}" "https://transfer.sh/${filename}")

        awk 'tolower($0) ~ /x-url-delete/ \
            { gsub("\r", "", $0); print "Delete command: curl --request DELETE " "\""$2"\""; \

My pleasure! 😃

If it is too big for the README.md, you may want to put it into an expandable detail section:

Some details

$ some_command

if you have time and you can open a PR to directly update the README.md it would be awesome

I'm a little busy this days and I'm not sure when I'll be able to do on my own 🙏
