Hi, not sure where the right place is for this post but if anyone has any ideas then please share :) I have a matlab script that runs daily and sends an email to show the results (the position of a buoy in the sea). If the matlab script fails - this is recorded in the email, however, if the...

Hi, Fedup of waiting half an hour for my dell mobile workstation to load up i removed some unused programs from the startup options in msconfig. When it restarted it came up with the usual ms panic and very low resolution. I couldn't change the resolution so i just went back to the normal...

hehe - no. Thanks PHV. i'm SO rusty with awk!

Thanks PHV, but i still can't get it to work. My layout is slightly different now (bin, ensemble, data....) so i've used: for(i=1;i<=(1+$1);++i)printf "%s,",$i;print $(2+$1) but all i get is extra blank space at the end and nothing removed. Can you offer further help? I've included the first...

Hi, I have columns of data which are measurements of current flow in the water column. The instrument returns data from above the water column, which is data I want to remove (retain only data in the water, not any noise). my datafile (headers): ensemble, depth, 1, 2, 3, 4,... 34, 35, 36, 37...

I haven't a clue really! I haven't used awk for a couple of years and so I am almost back to square one. I am currently trying to use the approach of converting the date and time into a number and then using a similar code to http://www.tek-tips.com/viewthread.cfm?qid=1329515 any ideas would be...

Hi, I have a file of burst data - i.e. data exists every 0.5 seconds for 1 minute, and then there is a 15 minute gap (approx) before any more data is printed. Can awk average the data (multiple columns) for each burst and print the line of averaged data to a new file? Input: 23/11/2008...

Thank you vlad, most apprieciated. rhnaeco

Hi, i need a bit of help sorting out my script: awk ' BEGIN { while (getline < "file1") { cnt[$1]=$1 dep[$1]=$2 } } { if (cnt[$1] = $1) if ((dep[$1] < $2+0.4) && (dep[$1] > $2-0.4)) print $1, $2, dep[$1], $3, $4 }' file2 > file3 lines from file1: 486 -0.35...

thank you - it works great! I kind of understand how it works but i do have one question/confirmation - what does the '%' mean in this context- i thought it was to do with decimal places but the results show 7dp rather than 5. google deosn't really like '%' as a search and i can't say i...

i can only see help for subsequent lines, not lines preceeding the label.....

hi, i have a data set of sonar pings. Each record consists of several lines of associate data such as depth and position and followed by 30 lines of actual data, followed by the next record. normally i would say something like ' if $1 = "line1" then print next 30 lines' and then sort it out...

Thanks Feherke, that explained it nicely- i was still none the wiser after wading through the awk man page! and thanks risby- i was definately on the right track if your answer is anything to go by, but i just couldnt 'join the dots ' so to speak. thanks again rhnaeco

thank you, thank you, thank you!! what does % do? (google is no help) this has been very frustrating for me as i had lots of components to this answer but couldn't for the life of me work out how they would all fit together! thanks again rhnaeco
