# Various small text manipulation utilities
## `cut`
Select fields from each line based on some delimeter
cut -d <delimiter> -f <list of fields>
Setting a different output delimiter:
--output-delimiter <delimiter>
## `comm`
comm file1 file2
Outputs three columns:
1. Lines unique to `file1`
2. Lines unique to `file2`
3. Lines in both files
Assumes files are sorted.
Suppress a column with e.g. `-1`.
So intersection of two files:
comm -12 file1 file2
## `diff`
Side by side:
diff -y
