I have a main.ksh that executes a perl script and which in turn spawns child ksh processes and awk scripts. I have main.ksh in crontab to run every 10 mins. Is there a way to make sure that neither an earlier version of main.ksh or ANY OF ITS CHILD PROCESSES are running when crontab starts...

I have a new requirment now. I want to be able to strip multiple columns from the flat file using awk. So it could be column 3 and 5 in the above example. If i pass the variable fld2delete with the value "3,5" would I be able to strip it within the awk program. The other...

Ygor, Sorry about that. It works fine for files with small number of columns. I had a file with 49 columns in it and I was trying to delete the 49th column and was unable to do it. I read in the sed man pages that sed cannot edit very long lines. Is sed reliable for long lines and how long...

Ygor, I used your solution in my application for stripping a column and it worked fine. However if you have a blank column in between it does not strip successfully. For example in the below data : 10/17/2003^F^444444^F^11^F^^F^1333^F^09-15-2003^R^ If I want to strip column 1 it gets...

Sorry for the late reply. I will try it and let you know. Thanks for your responses.

PHV, I tried your solution and ran into a few problems ... * the uniq file has only the last row in the input file and * the dups has all the rows including duplicates. Can you please explain your script?? Thanks for your help.

I have a text file with contents as follows that will be loaded into a database table: 600193439^_600076830^_600193439^_2^^ 600193430^_600076827^_600193430^_6^^ 600192222^_600076830^_600191112^_2^^ 600333333^_600076830^_600193111^_2^^ ... ... The table has columns 2 and 4 as the primary keys...

Simple question... * I have a a.tar.Z compressed file in directory A. * I want to uncompress and untar the files in a.tar.Z and put them in directory B. Is there a more efficient way than doing it in 3 steps... - cp A/a.tar.Z B/. - uncompress B/a.tar.Z - tar -xvf B/a.tar Thanks for your help.

Thanks to both vgersh99 and Ygor. Both your solutions worked great.

I got an answer to this from the AWK forum. Thanks.

vgersh99, Thanks for your quick response. I changed the FS to be "\\^F\\^" and OFS to be "^F^" in your script and tried it. It worked very well, except for the last column. For example when I specified the fld2delete=5 it did not delete the 5th field from the sample...

thanks for both your help guys. I used adam's solution since I had a for loop and had to pass the value of the variable for that iteration on click of the edit button.

I have a button and everytime the button is clicked I need to pass a string variable to the next jsp page. Can you please help me with a script for this : <INPUT type=&quot;button&quot; value=&quot;Edit&quot; onClick=&quot;????&quot;> Thanks for you help in advance.

CaKiwi, My problem is solved. Thanks for your prompt response.

CaKiwi thanks for your response. The script worked perfectly. An additional question. Instead of printing the 46th line before the pattern, can I search for the word &quot;Case:&quot; before the pattern 124304 and print that line. So if the file is as below ======== 06/18/2003 12:00:00:008...

Hi all. I have a fixed format log file with content as follows : ======== 06/18/2003 12:00:00:008 blah blah 06/18/2003 12:00:02:010 blah blah .. .. .. 06/18/2003 12:00:00:016 blah blah 06/18/2003 12:00:03:020 submission 124304 .. .. 06/18/2003 12:00:04:200 blah blah 06/18/2003 12:00:05:020...

Thanks for your help guys.
