Basic Prowershell Commands

2. cd - change directory.
3. cd .. - move to previous directory.

Git Bash Commands

(that I have used so far)

1. Command to read a URL page and return text data and then store it in data.txt file.

$ bash curl "https://www.hymnal.net/en/hymn/h/313" -O "data.txt"

2. Command to return \12 in place of ' ' and sort the data in data.txt in numeric, reverse order. This data is then stored in a new file called result.txt.

$ tr ' ' '\12' < "data.txt" | sort | uniq -c | sort -nr > "result.txt"

• I have used the following URL for data processing:

https://www.hymnal.net/en/hymn/h/313

3. Commands for Bash preview:

$ cat "result.txt"
$ head -5 "result.txt"
$ tail -2 "result.txt"

4. Commands for Powershell cat (I did not use these commands yet):

Get-Content "result.txt"
gc one.txt -head 2
gc one.txt -tail 2
