I agreed, initially. The texinfo documentation gives examples of how to convert seq output to hexadecimal (%x) using printf: -------------------- If you want hexadecimal integer output, you can use `printf' to perform the conversion: $ printf '%x\n' `seq 1048575 1024 1050623` fffff 1003ff 1007ff For very long lists of numbers, use xargs to avoid system limitations on the length of an argument list: $ seq 1000000 | xargs printf '%x\n' | tail -n 3 f423e f423f f4240 To generate octal output, use the printf `%o' format instead of `%x'. -------------------- > The OP wanted a little shell solution to create 50 directories > with a fixed prefix and suffix, so what about this? > > seq -w 50 | sed 's/^/prefix/; s/$/suffix/' | xargs mkdir Hmm... The first time I ran an example like the above, I used -w without realizing that there was no need, since the printf format would handle the fixed width part. (the disadvantage with this approach is that you have to pre-compute the width and use that number in the printf format, whereas in Bernie's example, that's done automatically by seq -w. This suggests that seq's --equal-width (-w) option *would* be handy in conjunction with the requested integer format directives. Then, we'd get the benefit of -w along with the more direct use of a seq format string. ) $ seq -w 12 | xargs printf 'a-%02x-b\n' a-01-b a-02-b a-03-b a-04-b a-05-b a-06-b a-07-b a-printf: 08: value not completely converted 00-b a-printf: 09: value not completely converted 00-b a-0a-b a-0b-b a-0c-b [Exit 123] That looks like a bug, but printf is actually required to reject those two input strings. A leading "0" means octal. This does what you want: $ seq 12 | xargs printf 'a-%02x-b\n' a-01-b a-02-b a-03-b a-04-b a-05-b a-06-b a-07-b a-08-b a-09-b a-0a-b a-0b-b a-0c-b

The texinfo documentation gives examples > of how to convert seq output to hexadecimal (%x) using printf: yes, i know there are numerous ways to post-process seq's output. I even included a few in my answer to the stackexchange question i linked to. if there's some reason why floating point is possible but the integer formats are not then fair enough....but it doesn't make sense to me to arbitrarily declare that floating-point printf support is OK but not integer. the examples using printf and xargs and so on are both obvious and missing the point. this bug report is not about them. it's about seq's incomplete support for printf. > (the disadvantage with this approach is that you have to pre-compute > the width and use that number in the printf format, whereas in Bernie's > example, that's done automatically by seq -w.

A leading "0" means octal. yeah, ran into that myself and thought WTF until i realised 'oh yeah. octal'. > $ seq 12 | xargs printf 'a-%02x-b\n' yep, but i already knew that. i'm not asking for help to solve a problem. I'm submitting a wishlist level bug report for a feature enhancement to support more of printf's formatting capabilities in seq. craig -- craig sanders <cas@HIDDEN>
