Top Forums UNIX for Advanced & Expert Users [BASH] Read value of variable, but not comment on the same line Post 302953583 by sea on Sunday 30th of August 2015 09:03:36 AM

Yikes true, happened because i had commented out the lower line in the testfile.
You asked why i added the ./ Smilie

Currently have:
Code:
+ tui $ bin/tui-conf-get -s tmp list
one two three four five six 
+ tui $ bin/tui-conf-get tmp list
1 2 3 4 5 6
+ tui $ cat tmp
variable=value # unwanted commend
list="one two three four five six" # bad comment
list='1 2 3 4 5 6'

I tried to also remove single quotes with the awk, and appended a tail, but it fails:
Code:
awk -F= -v VAR="$VARNAME" '$1 ~ "^[^#]*" VAR "$"{gsub ("#.*$|\"|\'|"$1 FS, ""); print}' "$CONFFILE" | tail -n1

But now fails with:
Code:
LC_ALL=C bin/tui-conf-get -s tmp list
bin/tui-conf-get: line 136: unexpected EOF while looking for matching `"'
bin/tui-conf-get: line 138: syntax error: unexpected end of file

As soon i remove the \'| it works again like:
Code:
LC_ALL=C bin/tui-conf-get -s tmp list
'1 2 3 4 5 6'

NAME
setup - A text mode system configuration tool SYNOPSIS
setup DESCRIPTION
The setuptool program (setup) is a front-end menu program for a group of other tools, mostly system-config-*-tui tools. The list of options which it presents is assembled by scanning /etc/setuptool.d and /usr/share/setuptool/setuptool.d for files. Each file in the directory should contain one or more lines of text. Each line contains from one to four fields which are separated by "|" characters. In order, they are: - the path to the binary to invoke (mandatory) - the untranslated name of the application which should be displayed (If unset, defaults to the path of the binary, but don't depend on that.) - the gettext textdomain in which a translation of the name of the application can be found (If unset, defaults to "setup".) - the directory in which translations for the textdomain can be found (If unset, defaults to "/usr/share/locale".) If multiple entries with the same untranslated name exist, the one which was read FIRST takes precedence. Files are read in name collation order. EXAMPLE
A contrived example would create /etc/setuptool.d/00bogus with these contents: /bin/ls --color; /bin/sleep 5|Example "ls" invocation. or /bin/ls --color; /bin/sleep 5|Give this help list|libc to use one of libc's (not meaningful here, but) translatable messages. Linux 2009-10-07 setup(1)
