sh - Check if a file exists with wildcard in shell script - Stack Overflow | https://stackoverflow.com/
You can do the following:
<code class="language-bash">
set -- xorg-x11-fonts*
if [ -f "$1" ]; then
printf "BLAH"
fi
</code>

This works with sh and derivates: ksh and bash. It doesn't create any sub-shell. $(..)and `...` commands create a sub-shell : they fork a process, and they are inefficient. Of course it works with several files, and this solution can be the fastest, or second to the fastest one.

It works too when there's no matches. There isn't need to use nullglob as one of the comentatators say. $1 will contain the origintal test name, therefore the test -f $1 won't success, because the $1 file doesn't exist.

Powerline Escape Fix [usevim.com] [archive.org]
Last week I wrote about Powerline Alternatives, and there was also a Hacker News thread about vim-airline where one of the posters had this useful tip about Powerline:

The delay in leaving insert mode used to drive me nuts in vim-powerline. I posted an issue and the author pointed me to this helpful Vim config snippet as a workaround (original link gone as the vim-powerline issue tracker has been removed, so reposting as a gist): https://gist.github.com/brendonrapp/5944296.

. It turns out Amazon is now using .kfx, which is not easily convertible, and the solution recommended by mobileread forums was to make sure my virtual Kindle is set to not automatically update to the latest version, uninstall the current Kindle-on-PC program, delete all the files in My Kindle Content, then find, download, and install an older version (1.17) which still uses .azw. It was a pain, but I did it, and now I can buy Amazon books again and convert them to read on my preferred reader, r...

CRAN - Package httpuv
There's no binary for httpuv-1.4.5 for R 3.3.3. So if you have a too-old RStudio on Windows, you won't be able to use shiny-1.2.0 (latest as of November 2018).

Workaround: install Windows / R 3.3.x shiny_1.0.5.zip (binary) from https://cran.r-project.org/bin/windows/contrib/3.3.

install - Error in R: (Package which is only available in source form, and may need compilation of C/C++/Fortran) - Stack Overflow
There were two good ideas here: 1) using Rtools (https://cran.r-project.org/bin/windows/Rtools/); and 2) using binaries from https://cran.r-project.org/bin/windows/contrib/3.3.

What I ended up doing to solve this problem (shiny-1.2.0 w/ R 3.3.3 on Windows required httpuv-1.4.5, but only 1.4.1 was available as a binary for R 3.3.x on CRAN), was to download the Windows binary shiny_1.0.5zip from the URL in #2 above.

[RFC] Add support for accepting a completion · wincent/YouCompleteMe@dfe7b81
This has come up before in a somewhat polemical thread here:

Valloric#232

The argument against adding this feature was basically:

> The keys can be remapped, but this is how it works. There is no accept
> key because it is unnecessary. I am not willing to change YCM to force
> the user to add unnecessary key presses just because "that's how other
> editors work".

How do I compile Readline support into Ruby - Stack Overflow | https://stackoverflow.com/
This is *NOT* work for me. I ended up using 'libedit' instead, after much exasperation, trials, and tribulations.

Editline Library (libedit) - Port of NetBSD Command Line Editor Library | http://thrysoee.dk/
ncurses is required for libedit (which is required when you can't get Ruby 2.5.something to build with readline).

In order to build libedit successfully, you either need to have your ncurses headers in the $PREFIX/include directory, or explicitly give CFLAGS *and* CPPFLAGS a '-I/path/to/your/include/ncurses', because ncurses itself puts its headers in a 'ncurses' subdirectory.

The 'CPPFLAGS' one was surprise to me, but if you don't you get this error message while './configure' runs:
<code>checking ncurses.h presence... no
configure: WARNING: ncurses.h: accepted by the compiler, rejected by the preprocessor!
configure: WARNING: ncurses.h: proceeding with the compiler's result</code>

How to pass password to mysql command line - Unix & Linux Stack Exchange | https://unix.stackexchange.com/
It doesn't look like you can send a password to 'mysql' on stdin, even though that's where it seems to be expecting it from with the '-p' (no password) option.

So I ended up using the '--defaults-file' option.

Index of /bin/linux/ubuntu | https://cran.r-project.org/
Some people have reported difficulties using this approach. The issue is usually related to a firewall blocking port 11371. If the first gpg command fails, you may want to try (thanks to Mischan Toosarani for the tip):
<code class="language-bash">
gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
</code>

and then feed it to apt-key with
<code class="language-bash">
gpg -a --export E298A3A825C0D65DFD57CBB651716619E084DAB9 | sudo apt-key add -
</code>

Another alternative approach is to search for the key at http://keyserver.ubuntu.com:11371/ and copy the key to a plain text file, say key.txt. Then, feed the key to apt-key with
<code class="language-bash">
sudo apt-key add key.txt
</code>

gnu make - makefile: concatenate text with infix operator - Stack Overflow | https://stackoverflow.com/


Louis is correct: there's no magical way of doing this. But if, instead of trying to remove the last item or treat it specially, you instead treat the first item specially, the work is much simpler to understand (I think); you can create a function combine that takes two arguments: the first is the text to put between the words and the second is a space-separated list of words to combine:
<code class="language-makefile">combine = $(word 1,$2) $(foreach W,$(wordlist 2,$(words $2),$2),$1 $W)</code>

Now you can use it like this:
<code class="language-makefile">$(call combine,-o,$(EXCLUDE_LIST))</code>

to get output like:
<code class="language-">$(BASE_DIR)/aaa* -o $(BASE_DIR)/bbb*</code>
