applescript with shell script having % " - shell

I have a long apple script that does conversion of files, moving files, compression etc.
I have to include a renaming script in-between the script that does rename files e.g. file1.pdf to file0001, file2 to file0002 and so on.
I found the following script works in terminal, but how can I include this in-between my applescript since it has percentage %, quotes " inside of the command.
works in terminal
rename 's/\d+/sprintf("%04d",$&)/e' ~/Downloads/test/*.pdf
I can't do shell script like this one
do shell script "rename 's/\d+/sprintf("%04d",$&)/e' " & theFolder & "*.pdf"
this will end up with error since it has percentage %, quotes ".
How can I implement this into my applescript, thanks.

do shell script quoted form of "rename 's/\\d+/sprintf(\"%04d\",$&)/e' ~/Downloads/test/*.pdf"

How to pass several variables from Shell Script to AppleScript in Automator?

There is an excellent answer for the reverse, pass several variables from AppleScript to Shell Script but I can't find a comprehensive answer for the opposite when there are two or more variables/arguments and or a bash function.
In Automator I am trying to pass variables like so: Run AppleScript > Run Shell Script > Run AppleScript.
Run AppleScript: which passes a URL as an argument
Run Shell Script: which uses "$#" for that argument
/bin/bash serial=$(($RANDOM % 10000)) /usr/local/bin/ffmpeg -i "$#" -c copy bsf:a aac_adtstoasc "/Path/to/file/movie_$serial.mp4" 2>&1 $! exit 0
Run AppleScript: This is where I need to pick up stdout, and the PID of the last executed process ffmpeg from Run Shell Script above. I can't seem to get anything. I have tried adding an automator "Storage Variable" but it's not receiving.
Using AppleScript's Do Shell Script command I couldn't get serial=$(($RANDOM % 10000)) to actually put a serial number in the file name movie_$serial.mp4. The file name was literally output as "movie_$serial.mp4", instead of "movie_1234.mp4".
serial=$(($RANDOM % 10000)) works perfectly in Terminal and in Run Shell Script. Not sure what I am missing to make it work with "Do Shell Script".
do shell script "/bin/bash serial=$(($RANDOM % 10000)); /usr/local/bin/ffmpeg -i " & link_ & ffmpegOpt & "'" & sPath & "$serial.mp4" & "'"
Which returns the following for the "do shell script" call:
"/bin/bash serial=$(($RANDOM % 10000)); /usr/local/bin/ffmpeg -i urlofmovie -c copy -bsf:a aac_adtstoasc '/Path/to/file/movie_$serial.mp4'"
When using ffmpeg the path on the command line the save path has to be in quotes.
If I read your OP correctly, you actually have two different issue here.
Not knowing how to provide input to a Run AppleScript action from a Run Shell Script action.
Variable parameter expansion is not occurring for you with: $serial
Issue 1:
To return something from a Run Shell Script action to another action. e.g. a Run AppleScript action, set the last line of the Run Shell Script action to, e.g.:
echo "foobar"
Or:
printf "foobar"
For multiple items use, e.g.:
echo "foobar
barfoo"
Or:
printf "foobar\nbarfoo"
Issue 2:
I am not in the position to replicate your do shell script command at the moment; however, the reason variable parameter expansion is not occurring is because the variable has single-quotes around it.
... '/Path/to/file/movie_$serial.mp4'"
Expansion will not take place when a variable has single-quotes around it, so you need to formulate your command so it can be expanded. Or in a separate step, process what's necessary to to accomplish the goal.
For example:
set sPath to "/path/to/file/movie_"
set serial to ((random number from 0 to 32727) mod 10000) as string
set pathFilename to sPath & serial & ".mp4"
Then you can use, e.g.:
... & pathFilename's quoted form
In your do shell script command while adjusting the entire command to work for you.
In other words, you can get rid of, e.g.:
/bin/bash serial=$(($RANDOM % 10000));
And:
& "'" & sPath & "$serial.mp4" & "'"
When running a shell script from Script Editor and wanting to return more than one argument as input; and assign those arguments to variables in your Apple Script:
One method I discovered:
Example shell script:
SHELL_VAR1=$(date)
SHELL_VAR2=$(whoami)
echo "$SHELL_VAR1","$SHELL_VAR2"
The echo command at the end, with a comma for delimiter, will output to Apple Script in this format:
{"January 21, 2022", "john"}
In the Apple Script:
set input to (do shell script "script.sh")
set the text item delimiters to ","
set {var1, var2} to {text item 1, text item 2} of the input
{var1, var2}
If there is another, simpler, method I would love to learn it.
Is there a special notation for multiple arguments that Apple Script can use for input?
i.e. $1 $2 or something similar

Applescript shell script to folder with space

I am trying to write a text file to a folder that contains space in the name. eg: folder 2
The first script that writes to folder works correctly
The second script that writes to folder 2 does not work correctly.
Edit:
I tried to use single quotes around the path and it works, if I hardcode the path. Is there a way to write to the folder without losing the ~ symbol?
--this works
do shell script "echo " & "the text" & " >> ~/Desktop/folder/text.txt"
--this does not work
do shell script "echo " & "the text" & " >> ~/Desktop/folder 2/text.txt"
This will work:
do shell script "echo " & "the text" & " >> ~/Desktop/folder\\ 2/text.txt"
Note: When using ~, which is the same as $HOME, in a do shell script and there is a space in the pathname, use a double backslash \\ to escape the space and do not quote the pathname containing a ~. In bash the space would only need a single backslash \ to escape the space.
This works too:
do shell script "echo " & "the text" & " >> \"$HOME/Desktop/folder 2/text.txt\""

How to deal with white spaces in osascript [duplicate]

This question already has answers here:
Combining variables in Bash to form a command sent to AppleScript using the osascript command
(2 answers)
Closed 5 years ago.
I'm in need of your assistance on how to deal with white space in a path.
In my example below, I'm setting some variables in a Terminal bash shell and executing, "osascript" from command line, utilizing these variables to run ['do shell script'] & ['display dialog']. When I run these from command line, I'm getting different results. My ultimate goal here is to be able to execute ['do shell script'] and it execute the bash shell script based on the path. In this case, the path has spaces in it.
NOTE: The INSTALLER_PATH variable defined below is set like this because the path is generated from an Apple Script I wrote that basically takes a path [ with white spaces in it ] and combines that path with another variable. Because this path has spaces in the name, I'm using the [ to quoted form of ] setting that puts the path in quotes.
APPLE SCRIPT EXAMPLE:
set pathToApp to POSIX path of ((path to me) as text)
set dragonFrame to ("_DRAGONFRAME/")
set INSTALLER_PATH to quoted form of pathToApp & dragonFrame
display dialog INSTALLER_PATH
GENERATES THIS PATH {notice the ticks}:
'/Volumes/Free.Space/Shotgun Python Dragon Project 2017/DRAGONFRAME_SCRIPTS_MASTER_V1.02/Dragonframe_Scripts_Installer.app/'_DRAGONFRAME/
Instead of testing this through the Apple Script to find the exact syntax I would need, I figured it would be easier to test this from command line. This is exactly what I'm setting and executing from my Terminal command line. In the examples below, executing [ 'display dialog' ] works and [ 'do shell script' ] fails. I think if there's a way to enclose the entire path in double quotation marks, my problem would be solved although all attempts at getting the path enclosed in double quotation marks has failed:
%> INSTALLER_PATH='/Volumes/Free.Space/Shotgun Python Dragon Project 2017/DRAGONFRAME_SCRIPTS_MASTER_V1.02/Dragonframe_Scripts_Installer.app/'_DRAGONFRAME/
%> ADMIN_USER_PROC="_Python_PySide_QT_Installer/Scripts/AdminUserProcesses.sh"
%> osascript -e 'do shell script ("'"${INSTALLER_PATH}"'" & "'"${ADMIN_USER_PROC}"'")'
GENERATES THIS ERROR:
0:217: execution error: sh: /Volumes/Free.Space/Shotgun: No such file or directory (127)
%> osascript -e 'display dialog ("'"${INSTALLER_PATH}"'" & "'"${ADMIN_USER_PROC}"'")'
GENERATES THIS PATH:
/Volumes/Free.Space/Shotgun Python Dragon Project 2017/DRAGONFRAME_SCRIPTS_MASTER_V1.02/Dragonframe_Scripts_Installer.app/_DRAGONFRAME/_Python_PySide_QT_Installer/Scripts/AdminUserProcesses.sh
Thank you in advance for any help you can offer.
I think you're looking for something similar to this syntax:
set dragonFrame to ("/_DRAGONFRAME/")
set INSTALLER_PATH to path of (pathToApp & dragonFrame)
Result:
'/Volumes/Free.Space/Shotgun Python Dragon Project 2017/DRAGONFRAME_SCRIPTS_MASTER_V1.02/Dragonframe_Scripts_Installer.app/_DRAGONFRAME/'
If you need double-quotes around the path you can use:
("\"" & pathToApp & dragonFrame & "\"")
and get rid of the quoted form argument leaving you with:
set INSTALLER_PATH to ("\"" & pathToApp & dragonFrame & "\"")

Applescript to get a list of file's hashes in a folder

I'm working on a script that will grab all files in a folder and compute their hash, however I'm having trouble on what should be one of the most basic parts of the script - concatenating found files into a shell script that will find the hash. Specifically, my problem is with this line:
do shell script "/usr/bin/openssl sha1 " & quoted form of POSIX path of new_file
It's line 44 of the script as a whole, here: http://pastebin.com/fEuFg9xL
My error is "Can't make quoted form of POSIX path of item 1 of {the list of files} into type unicode text".
Thanks in advance!
new_file is just a item of a list. You need it as text (like you already did couple of times in your code).
do shell script "openssl sha1 " & quoted form of POSIX path of (new_file as text)

How to pass a variable FROM applescript TO a shell script?

I have the following script
#!/bin/bash
/usr/bin/osascript << EOT
set myfile to choose file
EOT
no_ext=$(python -c "print '$myfile'.split('.')[0]")
### this works - just need to know how to pass the arg
R CMD Sweave no_ext.Rnw
pdflatex no_ext.tex
open no_ext.pdf
Can anyone point me to "how to pass the variable myfile correctly" ?
EDIT
Thx for all the suggestions!
Don't know what to accept, all of your answers really helped me since I learned a lot from everybody.
The following problems exist in your script:
A variable set in the AppleScript section does become defined in the enclosing shell script. You have to do the data exchange with the shell script by using command substitution.
AppleScripts invoked from a shell script aren't allowed to do user interaction because they do not have an application context. You can use the helper application "AppleScript Runner" to run user interaction commands.
Here is a revised version of your script where those problems are fixed:
#!/bin/bash
myfile=$(/usr/bin/osascript << EOT
tell app "AppleScript Runner"
activate
return posix path of (choose file)
end
EOT)
if [ $? -eq 0 ]
then
echo $myfile
else
echo "User canceled"
fi
First, you need to get the contents of the myfile variable from Applescript to bash. I don't know Applescript, so I'll make a shot in the dark as to how to write to its standard output. Then the python part is just unnecessary complexity (and likely wrong anyway, you were throwing away everything after the first . rather than the last). Next you need a $ before the variable name in bash syntax. I think the following script does what you want:
#!/bin/sh
set -e
myfile=$(osascript <<EOT
set myfile to choose file
write myfile to stdout
EOT
)
no_ext="${myfile%.*}"
R CMD Sweave "$no_ext.Rnw"
pdflatex "$no_ext.tex"
open "$no_ext.pdf"
(set -e at the beginning makes the shell exit immediately if an error occurs, instead of trying to execute pdflatex even though no .tex file has been produced or somesuch.)
Realize that applescript paths are colon ":" delimited. You need slash delimited in bash so in applescript terms that's the "posix path". Also, when using osascript it can't open dialog windows. You must tell an application to open the window. Next, you "return" something from the applescript... that's what goes to bash. Finally, in bash to execute a command and assign the result to a variable use `` around the command. So knowing this here's a shell script to use an applescript to get the myFile variable.
#!/bin/bash
myFile=`/usr/bin/osascript << EOT
tell application "Finder"
activate
set myfile to choose file with prompt "Select the file to use in bash!"
end tell
return (posix path of myfile)
EOT`
echo $myFile
