Fix the error in some csh scripts.

[hongy...@gmail.com]

On Ubuntu 22.10, I noticed that some system shipped environments initialization scripts have syntax or logic errors as follows:

werner@X10DAi:~$ . /etc/profile.d/debuginfod.csh
bash: debuginfod.csh.save: line 17: syntax error: unexpected end of file
werner@X10DAi:~$ . /etc/profile.d/gawk.csh
bash: alias: gawkpath_default: not found
bash: alias: `unsetenv AWKPATH; setenv AWKPATH `gawk -v x': invalid alias name
bash: alias: gawkpath_prepend: not found
bash: alias: `if (! $?AWKPATH) setenv AWKPATH ""; if ($AWKPATH ': invalid alias name
bash: alias: gawkpath_append: not found
bash: alias: `if (! $?AWKPATH) setenv AWKPATH ""; if ($AWKPATH ': invalid alias name
bash: alias: gawklibpath_default: not found
bash: alias: `unsetenv AWKLIBPATH; setenv AWKLIBPATH `gawk -v x': invalid alias name
bash: alias: gawklibpath_prepend: not found
bash: alias: `if (! $?AWKLIBPATH) setenv AWKLIBPATH ""; if ($AWKLIBPATH ': invalid alias name
bash: alias: gawklibpath_append: not found
bash: alias: `if (! $?AWKLIBPATH) setenv AWKLIBPATH ""; if ($AWKLIBPATH ': invalid alias name
werner@X10DAi:~$ . /etc/profile.d/vte.csh
bash: vte.csh.save: line 19: syntax error near unexpected token `!'
bash: vte.csh.save: line 19: `if ( ! $?prompt | ! $?tcsh | ! $?TERM | ! $?VTE_VERSION ) exit'

Below are the contents of the above scripts:

werner@X10DAi:~$ cat debuginfod.csh
# $HOME/.login* or similar files may first set $DEBUGINFOD_URLS.
# If $DEBUGINFOD_URLS is not set there, we set it from system *.url files.
# $HOME/.*rc or similar files may then amend $DEBUGINFOD_URLS.
# See also [man debuginfod-client-config] for other environment variables
# such as $DEBUGINFOD_MAXSIZE, $DEBUGINFOD_MAXTIME, $DEBUGINFOD_PROGRESS.

if (! $?DEBUGINFOD_URLS) then
set prefix="/usr"
set DEBUGINFOD_URLS=`sh -c 'cat "$0"/*.urls; :' "/etc/debuginfod" 2>/dev/null | tr '\n' ' '`
if ( "$DEBUGINFOD_URLS" != "" ) then
setenv DEBUGINFOD_URLS "$DEBUGINFOD_URLS"
else
unset DEBUGINFOD_URLS
endif
unset prefix
endif

werner@X10DAi:~$ cat gawk.csh.save
alias gawkpath_default 'unsetenv AWKPATH; setenv AWKPATH `gawk -v x=AWKPATH "BEGIN {print ENVIRON[x]}"`'

alias gawklibpath_default 'unsetenv AWKLIBPATH; setenv AWKLIBPATH `gawk -v x=AWKLIBPATH "BEGIN {print ENVIRON[x]}"`'

I'm not familiar with these csh syntax in them. Any tips to fix these problems?

You are running 'csh' scripts (that stem from Redhat) with a 'bash'.
So depending on who activated/called these scripts my suggestions are
to use a csh interpreter (as opposed to a bash) to call the scripts,
or, contact Redhat support if their distribution is buggy (which I'd
consider unlikely, though).

I was having hard time reading your post due it formatting
and I am very tied now. I do not know where the scripts
begin/end, maybe put each script in their own pastebin type
URL.

But a quick look at thss line for csh
set DEBUGINFOD_URLS=.....
is wrong, it seems to be using the '2>'
which is invalid for csh

I suggest you contact the distro maintainer of the scripts,
maybe file a bug report.

The line in question is:

set DEBUGINFOD_URLS=`sh -c 'cat "$0"/*.urls; :' "/etc/debuginfod" 2>/dev/null | tr '\n' ' '`

The "2>" is part of a string passed to sh to be executed.

And if you look at the parent article, you'll note that the OP was
invoking a csh script from bash, so of course it's going to have errors.
This was already pointed out more than a month ago.
