Title: Bash script, TCL 9.0, unable to execute, No such file or directory
Post by: rhermsen on April 03, 2018, 05:32:49 PM

Hi all,

Just to get my findings confirmed.
And maybe other scripts have the same mistake I made.


With TCL8.2.1 I was able to start a bash script which has an header #!/bin/bash (sha-bang). Even if I I'm using GNU Bash, the script is executed.

Code: [Select]

$ sudo /usr/local/etc/init.d/frr
Usage: /usr/local/etc/init.d/frr {start|stop|status|restart|force-reload|<priority>} [daemon] [instance]
       E.g. '/usr/local/etc/init.d/frr 5' would start all daemons with a prio 1-5.

$ head -n 2 /usr/local/etc/init.d/frr
#!/bin/bash
#

$ which bash
/usr/local/bin/bash

$ ls -la /bin/bash
lrwxrwxrwx    1 root     root            19 Apr  3 20:48 /bin/bash -> /usr/local/bin/bash

$ version
8.2.1


With TCL9.0 I used the same bash script (same header #!/bin/bash).

Code: [Select]

$ sudo /usr/local/etc/init.d/frr
sudo: unable to execute /usr/local/etc/init.d/frr: No such file or directory

$ head -n 2 /usr/local/etc/init.d/frr
#!/bin/bash
#

$ which bash
/usr/local/bin/bash

$ ls -la /bin/bash
ls: /bin/bash: No such file or directory

$ version
9.0

So the header of bash scripts need to change to:
#!/usr/local/bin/bash

No, it sounds like there might be a problem with the startup script for bash. What do you get for the following command:

Code: [Select]

cat /usr/local/tce.installed/bash

Hi Rich,

Thanks for your reply. So there should be a symlink installed /bin/bash pointing to /usr/local/bin/bash

Code: [Select]

$ cat /usr/local/tce.installed/bash
$


Code: [Select]

$ ls -la /usr/local/tce.installed/bash
-rwxrwxr-x    1 root     staff            0 Apr  4 19:14 /usr/local/tce.installed/bash
$


Code: [Select]

$ which bash
/usr/local/bin/bash
$


Code: [Select]

$ bash --version

Yes, that is correct. According to this the startup script is missing:
http://tinycorelinux.net/9.x/x86/tcz/bash.tcz.list

Based on this list from TC8:
http://tinycorelinux.net/8.x/x86/tcz/bash.tcz.list
The following files appear to be missing:

Code: [Select]

/usr/local/share/bash/.bashrc
/usr/local/share/bash/bashrc
/usr/local/tce.installed/bash
I will bring it to Juanitos attention.

This affects x86 and x86_64.

bash extensions reposted in the x86 and x86_64 repos - thanks for reporting this

Confirmed, bash script starts normally now. Tested on TCL x86.

Thanks.
