I think it may be faster to load data files if I presort them. I'm having trouble getting the sort command to work. Specifically when trying to use a pipe field delimiter...
For example, I want to sort the data file test.txt by the second column:
Code: Select all
bash-3.2$ cat test.txt G|1 H|50 K|22 I|2 B|300 Z|4 P|200 bash-3.2$ sort -t| +1 -1 test.txt > test1.txt bash: +1: command not found sort: option requires an argument -- t Try `sort --help' for more information. bash-3.2$
