awk
是否有助于将“输入”转换为“所需输出”?
输入
testing speed of encryption
test 0 (64 bit key, 16 byte blocks): 2250265 operations in 1 seconds (36004240 bytes)
test 1 (128 bit key, 64 byte blocks): 879149 operations in 1 seconds (56265536 bytes)
test 2 (128 bit key, 256 byte blocks): 258978 operations in 1 seconds (66298368 bytes)
test 3 (128 bit key, 1024 byte blocks): 68218 operations in 1 seconds (69855232 bytes)
test 4 (128 bit key, 8192 byte blocks): 8614 operations in 1 seconds (70565888 bytes)
test 10 (256 bit key, 16 byte blocks): 1790881 operations in 1 seconds (3654096 bytes)

最佳答案
使用 column
右对齐的一个技巧是使用 rev
:
$ head -1 file; tail -n+2 file | rev | column -t | rev
