Top Forums Shell Programming and Scripting Remove carriage return from the variable Post 302878429 by RudiC on Friday 6th of December 2013 06:03:55 AM

Please be careful - that trick with awk works because when converting a field to a numerical value, awk will start at the beginning of the field and scan until an unconvertible char is encountered - which is "\" "r" in post#2. Yes - it's not <CR> but two normal chars.
Code:
 a="2.80985e+09\r\r\n"
echo $a xxx
2.80985e+09\r\r\n xxx
a="2.80985e+09"$'\r'
echo $a xxx
 xxx985e+09

The second assignment really has a <CR> char in it, making echo overprint the first chars.
To remove the <CR>, you can try this bashism (pattern substitution expansion):
Code:
echo ${a/$'\r'} xxx
2.80985e+09 xxx

or e.g.
Code:
echo $a  |hd
00000000  32 2e 38 30 39 38 35 65  2b 30 39 0d 0a
echo $a |tr -d '\r' |hd
00000000  32 2e 38 30 39 38 35 65  2b 30 39 0a

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME
libbash -- A bash shared libraries package. DESCRIPTION
libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may want to load and use in scripts of your own. It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries. Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1). A bash shared library that can be loaded using ldbash(1) must answer 4 requirments: 1. It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash). 2. It must contain a line that begins with '#EXPORT='. That line will contain (after the '=') a list of functions that the library exports. I.e. all the function that will be usable after loading that library will be listed in that line. 3. It must contain a line that begins with '#REQUIRE='. That line will contain (after the '=') a list of bash libraries that are required for our library. I.e. every bash library that is in use in our bash library must be listed there. 4. The library must be listed (For more information, see ldbashconfig(8)). Basic guidelines for writing library of your own: 1. Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions. 2. Try to declare all variables intended for internal use as local. 3. Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with: __<library_name>_ For example, internal function myfoosort of hashstash library should be named as __hashstash_myfoosort This helps to avoid conflicts in global name space when using libraries that come from different vendors. 4. See html manual for full version of this guide. AUTHORS
