Opening first few lines of a huge file with VS Code


I’m currently doing some work looking at the GeoNames dataset.
allCountries.txt is around 1.5gb, which is pretty large, and certainly too large to open up in vscode for a quick look.

However, I found I could use head command, which reads the first n lines of a file, and pipe the output to code - (which is the command for opening vs code and reading the output from another program)

For example:

$ head -3 allCountries.txt | code –

This opens the first 3 lines of allCountries.txt in vs code. Handy!
