Bash and zsh alias for transfer.sh. Transfers files and directories to transfer.sh.

Thank you so much for taking the time to lay this out as clearly as possible. This functionality is awesome, and I definitely look forward to using it on a day-to-day basis!

Thanks! Updated it to upload folders as well.

This alias function works great with Zsh. Many thanks!

I get the following error on both my RPI2 running Raspbian as well as on my Mac running OS X Yosemite:
bash: ((: ! $+commands[curl] : syntax error: operand expected (error token is "$+commands[curl] ").
Seems like it has something to do with the first IF statement so I just removed that (which helped) but still thought you might want to know about this.

$+commands[curl] is a zsh thing and doesn't work in Bash.

Thx, fixed it.

On Mac OS X Yosemite the bash script will always create a file named 1.

I beleive line 8 should be:

curl --version 2>&1 > /dev/null

thx, fixed

Thanks for this! Already used here.

Hi, I added a line on the bash version, to copy the link to clipboard...
If I just pipe it without the extra line, it doesn't show on terminal, so DRY suffered a bit.
Awesome product, thanks!

cat $tmpfile | pbcopy
cat $tmpfile

@bitbonsai, nice idea! Remove the newline at the end: cat $tmpfile | tr -d '\n' | pbcopy

Is there a version of.Bat?

Nice. However quotes are missing around $file (4 occurrences).

need to add a "-e" to echo for bash to interpret the newlines "\n".
Also looks like there's a redundant 'echo' in there?

Thank you so much for this service. You are beyond awesome. Wish I found out about it sooner!

Update: You can see my suggestions in my fork: https://gist.github.com/nl5887/a511f172d3fb3cd0e42d

I am using an older version of this alias. I tried to upload a file which its name contained brackets. I got an error because brackets have some special meaning for curl, apparently. So I suggest calling curl with -g switch to make it treat brackets in filenames as normal characters.

Any idea why I get:

syntax error near unexpected token 'filename'

After adding the alias and trying to call it with any parameter?

why not add transfer $1 at the end so its self executing and one can just add the file somewhere on the PATH?

Hello! How can one properly modify this shell script to add GPG encryption functionality ? It would be really nice to have this as an option.

$ transfer "Name With Spaces.txt"
result in

basename: extra operand 'Spaces.txt'
Try 'basename --help' for more information.

on the website's version, the gist works well ;D

Agreeing with @tallinn-code, it could be great to implement a .trshrc file ;D

There are several double quotes missing, plus other mistakes as in usage.
Here's the correct (bash) code:

transfer() { 
    # check arguments
    if [ $# -ne 1 ]; 
    then 
        echo -e "Wrong arguments specified. Usage:\ntransfer /tmp/test.md\ncat /tmp/test.md | transfer test.md"
        return 1
    fi

    # get temporary filename, output is written to this file so show progress can be showed
    tmpfile="$( mktemp -t transferXXX )"
    
    # upload stdin or file
    file="$1"

    if tty -s; 
    then 
        basefile="$( basename "$file" | sed -e 's/[^a-zA-Z0-9._-]/-/g' )"

        if [ ! -e $file ];
        then
            echo "File $file doesn't exists."
            return 1
        fi
        
        if [ -d $file ];
        then
            # zip directory and transfer
            zipfile="$( mktemp -t transferXXX.zip )"
            cd "$(dirname "$file")" && zip -r -q - "$(basename "$file")" >> "$zipfile"
            curl --progress-bar --upload-file "$zipfile" "https://transfer.sh/$basefile.zip" >> "$tmpfile"
            rm -f $zipfile
        else
            # transfer file
            curl --progress-bar --upload-file "$file" "https://transfer.sh/$basefile" >> "$tmpfile"
        fi
    else 
        # transfer pipe
        curl --progress-bar --upload-file "-" "https://transfer.sh/$file" >> "$tmpfile"
    fi
   
    # cat output link
    cat "$tmpfile"
    echo

    # cleanup
    rm -f "$tmpfile"
}

Thanks @HacKanCuBa ! Had the same problem.

Please consider pulling in my change:

(currently no way to do a PR on gists.. :( )

Consider replacing the fish version with a link to https://github.com/fisherman/transfer

Yeah, this should be a real repo, for PR's.

Please, always use http://shellcheck.net/ on shell scripts.

You can get it immediately in vim on Ubuntu/Debian with sudo apt install shellcheck vim-syntastic, also supported in lots of other editors, or just paste your script into the web site.

I added the following after '# cat output link' and before '# cleanup' to keep track of hem:

    # log file link
    APPLICATION="${0##*/}"
    RIGHTNOW="$(date)"
    EXPIRES="$(date -d "+14 days")"
    echo -e "$(cat "$tmpfile") - uploaded $RIGHTNOW - expires $EXPIRES\n" >> ~/$APPLICATION.log
    echo "See ~/$APPLICATION.log for all transfers."

solution without temp files

transfer() { 
    # check arguments
    if [ $# -eq 0 ]; then 
        echo "No arguments specified." >&2
        echo "Usage:" >&2
        echo "  transfer <file|directory>" >&2
        echo "  ... | transfer <file_name>" >&2
        return 1
    fi
    
    # upload stdin or file
    if tty -s; then 
        file="$1"
        if [ ! -e "$file" ]; then
            echo "$file: No such file or directory" >&2
            return 1
        fi
        
        file_name=$(basename "$file" | sed -e 's/[^a-zA-Z0-9._-]/-/g') 
        
        # upload file or directory
        if [ -d "$file" ]; then
            # transfer directory
            file_name="$file_name.zip" 
            (cd "$file" && zip -r -q - .) | curl --progress-bar --upload-file "-" "https://transfer.sh/$file_name" | tee /dev/null
        else 
            # transfer file
            cat "$file" | curl --progress-bar --upload-file "-" "https://transfer.sh/$file_name" | tee /dev/null
        fi
    else 
        # transfer pipe
        file_name=$1
        curl --progress-bar --upload-file "-" "https://transfer.sh/$file_name" | tee /dev/null
    fi
}

@qoomon
Both code from transfer.sh and your code return a link with a % at the end, making the link fail to open when opened by just click the link in Terminal output. I have to manually remove the % from address after pasted in address bar in a browser.
I am using zsh and add the function in ~/.zshrc. What could be the reason?

not working on bash for me from alpine or ubuntu 18.04. why? 😕
