Adding text files

If you have many files with text information, it is easier to look for what you need, if
all the info is assembled into a single file. To achieve this in Bash, you can do the following:

cat $(ls) > dictionary.txt

view raw merge_txt_files.sh hosted with ❤ by GitHub

this will put all files from the current directory into one file.
More complicated manipulations, such as sorting and elimination of duplicates,
described here.
