Is there a way to redirect each string output to standard out to another command?
// Example file: example.js
#!/usr/bin/env node
process.stdout.write('foo')
process.stdout.write('bar')
After running ./example.js | wc -m, the total character count of both foo and bar combined is 6.
I would like to see the counts separately as 3 and 3. Is there anything specific I need to change within my javascript file or in the command itself?
wc -m is a command that counts the number of characters in its input. It does not have the capability to separate or group by line. This function has no relation to your JS code.
If you want to achieve a different type of counting, you can easily do so with node.js!
In the case that your content is stored in a file with spaces and line breaks, and you need to count the characters in each file:
//example.js
#!/usr/bin/env node
process.stdout.write('foo')
process.stdout.write('~') // print any delimiter which is not part of your files content
process.stdout.write('bar')
//Use awk to split them and count as usual
./example.js | awk 'BEGIN { RS="~" } {print}' | wc -m
3
3
//Or use awk to remove spaces and get character count
./example.js | awk 'BEGIN { RS="~" } {gsub(" ", "", $0); print length}'
I hope this solution works for your needs.
