Does anybody here know how to run scripts with Termux?

[bat999]

Hi
See this very simple bash script…

#!/bin/bash
echo "Hello World"

With my Linux PC…

1
Make the file executable…
$ chmod +x filename

2
Run the script…
$ ./filename

The reply is…
Hello World

But when I try this with Termux it gives reply…
$ bash: ./filename: Permission denied

I have read some information about this at
https://wiki.termux.com/wiki/Termux-fix-shebang
and
https://wiki.termux.com/wiki/Termux-exec

But I can’t get it to work.

How do I make a “Hello World” script for Termux and how do I make it run?

Make sure that the current working directory matches the directory of the file. I guess you moved the file to /sdcard/filename. Termux, by default, starts somewhere like /data/data/com.termux/files/home/termux.

Also, in Permissions give it Storage, so then you can put your script anywhere (as allowed by Android):

You can’t make external storage file executable. If your file on external storage either move it to termux home directory or execute like this bash filename

Thanks shubhamtyagi

Yes, I can run the script if I use…
bash filename
or
sh filename

(whether it is executable or not)

“filename” is in “shared” directory not “termux home” directory.

“termux home” directory is higher up the hierarchy than “shared”.
I don’t think that I can put files in “termux home” because it doesn’t show in my file manager.
Maybe I would need a rooted phone to do that.

I suppose that “storage” and “storage/shared” is viewed as “external storage” by Termux.

See the hierarchy…
files → home → storage → shared → “filename”

$ ls
app_textures  code_cache  shared_prefs
app_webview   files
cache         lib
$ cd files
$ ls
home  usr
$ cd home
$ ls
storage
$ cd storage
$ ls
dcim       movies  pictures
downloads  music   shared
$ cd shared
$ ls
Android    Movies         Xiaomi
DCIM       Music          fac_sources
Documents  Pictures       filename
Download   Scripts
MIUI       SoundRecorder
$ bash filename
Hello World
$ sh filename
Hello World
$

1 So start Termux.

2 Then cd to storage/shared.

3 Then run bash filename or sh filename.

Is that the solution?

Termux can run script from widget. Just put the script in home/.shortcuts then you can add a widget for it.

@bat999

I don’t think that I can put files in “termux home” because it doesn’t show in my file manager.

My AOSP file manager can access termux home dir via SAF.

Is this working?

If not then copy your file to termux home (or wherever other than external storage).

@shubhamtyagi

Yes, that’s fixed it.

Copied filename from storage/shared to Termux home…

$ cp storage/shared/filename .
$ ls
filename storage

Tried to run it…

$ ./filename
bash: ./filename: Permission denied

Made it executable…

$ chmod +x filename

Ran it OK…

$ ./filename
Hello World

$ cp storage/shared/filename .
$ ls
filename storage
$ ./filename
bash: ./filename: Permission denied
$ chmod +x filename
$ ./filename
Hello World
$

Yes, that works for me too.
Thanks
