RE: newby stupid question - cat mutiple files to new piped output files
How about:
--- 8< cut here ---
#!/bin/bash
pushd /cygdrive/d/pc1
for file in *.csv; do
if [ "${file##new_}" != "${file}" ]; then next; fi
cat "${file}" | uniq > "new_${file}"
done
popd
---
I Guess bas is like perl: TIMTOWTDI ;)

Apart from that, you will overwrite the new file each time ;-)
$ for i in /cygdrive/d/pc1/*.csv; do cat $i | uniq >
/cygdrive/d/pc1/$1.new; done
Now you avoid that your new files are picked also and all new files have
new names (a .new appended).
Other approaches to do something like that:
find /cygdrive/d/pc1/*.csv -exec uniq \{} \{}.new \;
refer the manuals ...

Why not use mkcygwget. It's what I do to create my Cygwin installation CDs...

RE: OT: Using sed - guru help wanted.
Hi guys, sorry if this thread was dead but couldn't resist. Besides, it makes the start of my workday just that more bearable... :) (regular expressions for fun and profit eh) Simply sed: sed 's#^ *\(.*[^ ]\) */ *\(.*[^ ]\) *$#.\1.\2.#' Simply perl: perl -pe 's/^\s*(.*\S)\s*\/\s*(.*\S)\s*$/.$1.$2./' Both will split at the slash and strip leading/trailing spaces from the parts, even if a part contains just a single non-whitespace character, even if there is no whitespace to remove. Simple explanation: at start of string; zero or more spaces; string of zero or more characters; non-space character; zero or more spaces; slash; zero or more spaces; string of zero or more characters; non-space character; zero or more spaces; at end of string. HTH, Erik As it seems my query wasn't that well formed... i.e. remove any leading and/or trailing spaces on the parts. Parts separated by the slash. This seems to do exactly what I'm after; $ echo 'a b/c d e ' | \ sed -re 's- *(.*[^ ]) */ *(.*[^ ]) *$-.\1.\2.-' Thanks for the input, Brian and Igor. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/ -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
/proc/partitions question
Sorry, lost the previous mail so can't continue the thread. I took a look at the sources as cgf suggested and have the following question: in fhandler_proc.cc revision 1.36, in function format_proc_partitions() : after getting the drive geometry with 'IOCTL_DISK_GET_DRIVE_GEOMETRY' the size of the disk is calculated in bytes and this number is right-shifted 6 bits, so that's a division by 64 and that maps with the scaling difference of 16 between df and /proc/partitions. likewise after getting the drive's partition layout with 'IOCTL_DISK_GET_DRIVE_LAYOUT' the length of each parititions (which is in bytes) is again right-shifted 6 bits. So why the right-shift 6 instead of 10 which would map with a blocksize of 1K? If this is an obvious or trivial thing or if this has been addressed on the mailing list before or on some website: I apologise. I'm neither a windows nor a cygwin developer and I have little time but this just struck me as a bit weird. Erik. PS: if the layout of this mail looks weird I blame it on Lotus Notes which I am forced to use here at work. :( -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
