Read a file one line at a time in node.js?
...tion processLineByLine() {
const fileStream = fs.createReadStream('input.txt');
const rl = readline.createInterface({
input: fileStream,
crlfDelay: Infinity

// Note: we use the crlfDelay option to recognize all instances of CR LF
// ('\r\n') in input.txt as a single line break...
Bash foreach loop
...
Something like this would do:
xargs cat <filenames.txt
The xargs program reads its standard input, and for each line of input runs the cat program with the input lines as argument(s).
If you really want to do this in a loop, you can:
for fn in `cat filenames.txt`; do

The way to check a HDFS directory's size?
...ork (in Hadoop 2.7.1). For example:
Directory structure:
some_dir
├abc.txt
├count1.txt
├count2.txt
└def.txt
Assume each file is 1 KB in size. You can summarize the entire directory with:
hdfs dfs -du -s some_dir
4096 some_dir
However, if I want the sum of all files containin...
node.js: read a text file into an array. (Each line an item in the array.)

readLines(input, func);
EDIT: (in response to comment by phopkins) I think (at least in newer versions) substring does not copy data but creates a special SlicedString object (from a quick glance at the v8 source cod...
