Full Discussion: Stripping of a symbol from string not working properly
Top Forums Shell Programming and Scripting Stripping of a symbol from string not working properly Post 302615377 by Scrutinizer on Thursday 29th of March 2012 12:10:24 PM

That's because of both the double quotes and those pesky backticks (I don't understand why anyone would still want to use them, unless they are forced to by their ancient shell).
Code:
a=$(echo "$a" | sed -e 's/\$//g')

Code:
a=$(echo "$a" | sed -e "s/\\$//g")

Code:
a=`echo "$a" | sed -e 's/\\$//g'`

Code:
a=`echo "$a" | sed -e "s/\\\\$//g"`

strip

STRIP(1)						    BSD General Commands Manual 						  STRIP(1)

NAME

     strip -- discard information from ELF objects

SYNOPSIS

     strip [-d | -g | -S | --strip-debug] [-h | --help] [--only-keep-debug] [-o outputfile | --output-file=outputfile] [-p | --preserve-dates]
	   [-s | --strip-all] [--strip-unneeded] [-w | --wildcard] [-x | --discard-all] [-I format | --input-target=format]
	   [-K symbol | --keep-symbol=symbol] [-N symbol | --strip-symbol=symbol] [-O format | --output-target=format]
	   [-R sectionname | --remove-section=sectionname] [-V | --version] [-X | --discard-locals] file ...

DESCRIPTION

     The strip utility is used to discard information from ELF objects.

     The strip utility supports the following options:

     -d | -g | -S | --strip-debug
	     Remove debugging symbols only.

     -h | --help
	     Print a help message and exit.

     --only-keep-debug
	     Remove all content except that which would be used for debugging.

     -o outputfile | --output-file=outputfile
	     Write the stripped object to file outputfile.  The default behaviour is to modify objects in place.

     -p | --preserve-dates
	     Preserve the object's access and modification times.

     -s | --strip-all
	     Remove all symbols.

     --strip-unneeded
	     Remove all symbols not needed for further relocation processing.

     -w | --wildcard
	     Use shell-style patterns to name symbols.	The following meta-characters are recognized in patterns:
	     !	   If this is the first character of the pattern, invert the sense of the pattern match.
	     *	   Matches any string of characters in a symbol name.
	     ?	   Matches zero or one character in a symbol name.
	     [	   Mark the start of a character class.
	     	   Remove the special meaning of the next character in the pattern.
	     ]	   Mark the end of a character class.

     -x | --discard-all
	     Discard all non-global symbols.

     -I format | --input-target=format
	     These options are accepted, but are ignored.

     -K symbol | --keep-symbol=symbol
	     Keep the symbol symbol even if it would otherwise be stripped.  This option may be specified multiple times.

     -N symbol | --strip-symbol=symbol
	     Remove the symbol symbol even if it would otherwise have been kept.  This option may be specified multiple times.

     -O format | --output-target=format
	     Set the output file format to format.  For the full list of supported formats, please see the documentation for function
	     elftc_bfd_find_target(3).

     -R sectionname | --remove-section=sectionname
	     Remove the section named by the argument sectionname.  This option may be specified multiple times.

     -V | --version
	     Print a version identifier and exit.

     -X | --discard-locals
	     Remove compiler-generated local symbols.

DIAGNOSTICS

     The strip utility exits 0 on success, and >0 if an error occurs.
