No problems with many sizes, Cygwin or Windows sort, under bash or dash. Have you checked for permissions problems on $TMPDIR if set, or /tmp? My TMPDIR=/tmp - try: $ ls -dl $TMPDIR /tmp drwxrwxrwt+ 1 <USER> Users 0 Nov 29 15:24 /tmp ... $ getfacl $TMPDIR /tmp # file: /tmp # owner: <USER> # group: Users # flags: --t user::rwx group::rwx other:rwx default:user::rwx default:group::r-x default:other:r-x ... $ icacls `cygpath -m $TMPDIR` C:/<PATH>/tmp NULL SID:(DENY)(Rc,S,RD) <HOST>\<USER>:(F) BUILTIN\Users:(RX,W) Everyone:(RX,W) CREATOR OWNER:(OI)(CI)(IO)(F) CREATOR GROUP:(OI)(CI)(IO)(RX) Everyone:(OI)(CI)(IO)(RX) $ icacls `cygpath -m /tmp` ... and maybe try specifying an explicit temp dir using e.g. sort -T $HOME/ Maybe also check if any limits: $ ulimit -a core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited open files (-n) 256 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 2032 cpu time (seconds, -t) unlimited max user processes (-u) 256 virtual memory (kbytes, -v) unlimited Maybe try reinstalling coreutils in a standalone setup run? -- Take care.
