Bash to match and store line as variable
Post 302989778 by cmccabe on Wednesday 18th of January 2017 06:42:08 AM

The modification date is being used in the bash to determine the oldest file.
3 .tar.bz2 folders are downloaded and extracted by aria2cand the modification time of each folder is read by the bash.
That value starts with R_ always is stored as $filename but does not carry over the subsequent lines, so they don't execute.
Since $filename is written to the output log in the post, maybe it could be extracted? The problem is there could be multiple lines in that log, but only one $filename. That the variable needed for the subsequent lines. Thank you very much

Example output:
/tmp/generatelines.sh
line1
line2
line3
line4
I want each output line assigned to its own variable, ie:
"line1" --> $a
"line2" --> $b
"line3" --> $c
"line4" --> $d
Is this possible without writing to a temporary file?
Thanks (4 Replies)

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
