[hhnr]

any reason you are using csh script in the first place?

[kaushalmodi]

@rdotdk work

[hhnr]

Work laptop? Okay. Let me guess RHEL?

[kaushalmodi]

Work laptop?

Sort of, virtual machine.

RHEL?

Yup

I went ahead and replaced git_force_update.csh with force_update_emacsd.sh.

https://github.com/kaushalmodi/.emacs.d/commit/646b859885f7980624e4504372540fd844adb8a3

In tcsh, I use this alias:

alias update_emacs_config '(set e="/tmp/${USER}_force_update_emacsd.sh" \\
                           && curl https://raw.githubusercontent.com/kaushalmodi/.emacs.d/master/force_update_emacsd.sh >! $e \\
                           && chmod 0755 $e \\
                           && $e \!:1)'

[hhnr]

@kaushalmodi the script seems to fail with ./force_update_emacsd.sh: [[: not found error. I think the first line #!/bin/sh should be #!/bin/bash.

[kaushalmodi]

@rdotdk Thanks for trying. RHEL probably has sh symlinked to bash. So I didn't notice it. Let me see if I can use [ instead of [[. If not, will change the shebang to bash.

Of course it is :)

As I cannot try the "real sh" on my system, I am going with what you suggested.

@rdotdk Try out after updating to https://github.com/kaushalmodi/.emacs.d/commit/cc6e09dd5fcc863bb7d7d16dc2c5325e98693875

Works without any errors. Tested with bash on Ubuntu system.

RHEL probably has sh symlinked to bash.

In case of debian based systems it is symlinked to dash.

hari@hari-laptop:~$ ll /bin/sh

Thanks for confirming!

[kaushalmodi]

Note to self: Never use #!/bin/sh in shebangs.

[hhnr]

Yes. Also the paths shouldn't be mentioned directly in the shebang, instead #!/usr/bin/env bash should be used for portability.

[kaushalmodi]

Thanks, I was almost going to do that as I do the same for perl. I assumed that bash would be fine.

But there you go ( https://github.com/kaushalmodi/.emacs.d/commit/bd1131207035c3cf2032e78651febeea6e71e469 ). I cannot not do the right thing. :)
