Re^8: perllocale weirdness, bug, or...?

Thanks for the tip - I really hoped it might solve the issue, but unfortunately it does not.

For the file test.txt (TAB separated fields) being

a_2     2
a2      1
[download]

I still get

$ sort -k 1,1 test.txt | cut -f 1
a2
a_2
[download]

whereas when there is no second field then the result is reversed,

a_2
a2
[download]

Looks like the problem 'survives'.

Looks like two level sort: on the first level, it ignores the _, but if the strings are different only thanks to the underscore, it is used in the second level. `$ echo $'a_2\t2\na2\t1' \| sort -k1 a2 1 a_2 2 $ echo $'a_2\t2\na2\t1' \| sort -k1,1 a2 1 a_2 2 $ echo $'a2\t2\na_2\t1' \| sort -k1,1 a2 2 a_2 1 $ echo $'a2\t2\na_2\t1' \| sort -k1 a_2 1 a2 2` [download]	[reply] [d/l]
