In file2, assuming field2 is unique, read file2 into an array. Then, read file1 checking if each array element is between file1 and field2: awk ' BEGIN { while( getline < "file2" ) arr[$2]=$1 } { for(ind in arr) if(arr[ind] > $1 && arr[ind] < $2) print arr[ind]" "ind } ' file1

Save the call to awk: xargs -n 2 < U1414_velocity_function.txt

I recommend using something like this: # UNTESTED! find . -name "RECPT-ZONE*" |xargs rm -f -exec rm ... generates a Unix process for each file removed where xargs generates only one and xargs guarantees not to overflow the command line.

Travis: I assumed he meant to copy the directory structure, but you might be right; maybe he wanted all files copied to a seperate directory. Anyway, back in the day before Linux I used cpio a lot because of portability issues with tar. You can copy a directory structure using tar: cd...

...directory: cd /usr/my; find . -depth -print|cpio -pd /usr/mynew What constitutes a text file - a file with a text extension? You can search just for files with a text extension something like this: # UNTESTED cd /usr/my; find . -type f -name "*.txt" -depth -print|cpio -pd /usr/mynew

...the string and uses timelocal to return # the number of seconds from the Epoch. # No error checking! function seconds_from_epoch { echo $*| perl -MTime::Local -ane ' my $epochseconds = timelocal($F[5], $F[4], $F[3], $F[2], $F[1] - 1, $F[0]); print "$epochseconds\n"; ' } dt1=20120915...

Since your data is on Windows and database is on Unix, why don't you look at a client-server solution like Ab Initio. A.I. programming is done with a Graphical Development Environment. There is a learning curve, but it's window's programming - not Unix scripting. Ab Initio has a website you...

One way to create a shell script which dynamically creates the awk script based on a string - "8 21 34 47" in this case. Obviously there are enhancements that can be done to this: #!/bin/ksh file_name="theawk.ss" echo "nawk ' BEGIN { FS=\",\" } { for(i=1; i <=NF; i++) { " > $file_name...

Let me try it again: #!/bin/ksh nawk ' BEGIN { FS="," } { for(i=1; i <=NF; i++) { if(i < 8 || (i > 8 && i < 21) || (i > 21 && i < NF ) ) printf("%s,", $i) if(i == NF) printf("\n") if( (i == 8) || (i == 21) ) printf("%s,%s,", $i,$i) } } ' mydata55.txt

I find it easier to print out each field and then duplicate fields 8 and 21. Older awks have a limitation on the number of fields that awk supports, but this works for nawk on Solaris: #!/bin/ksh nawk ' BEGIN { FS="," } { for(i=1; i <=NF; i++) { if(i < 8 || (i > 8 && i < 21) || (i >...

'whoami' should work, but this parses the id command to get the real user: # get the real user id realuser=$(id|sed -e 's,^[^(]*(,,' -e 's,).*$,,' -e 1q) case $realuser in root | olded ) echo "root or olded" ;; *) echo "blah" exit 0 ;; esac

jdespres: I prefer the awk solution, but sed is possible: sed -e '6,$!d' -e 'N;$!P;$!D;$d' mydata.txt|sed '1!G;h;$!d'

Or ... lsvg|xargs

I take it you have redirected to a file to see if you have an error? This link offers two alternate commands that might work: http://www.linuxquestions.org/questions/aix-43/how-do-i-get-a-cronjob-to-run-every-two-hours-in-aix-00-*-2-*-*-*-command-no-work-763034/

I don't have time to help you right now, but this link should help: http://main.rtfiber.com.tw/~changyj/sed/html/p.20080725a.html

feherke: Thank you. That was helpful. Ed

Using perl's matching operator, I can extract lines 3, 6, and 9 from a file: perl -wnl -e 'print if $. !~ m/^(3|6|9)$/' datafile.txt Is there syntax for the matching operator that allows deleting a range of lines, say from 3 to 9? Thanks! Ed

This works assuming you are using ksh (or maybe bash): export PS1=${USER}@`uname -n`':${PWD} % ' I think you need to NOT escape ${PWD}

crasho: While on Solaris, try using nawk instead of awk.
