Hello all,

I am trying to remove the spaces in between the fields and the file is a "|" delimeter one.

ex :
i/p is
xxx | 2007-02-28 | 2007-02-28 | | | 1
o/p should be

xxx|2007-02-28|2007-02-28|||1

I tried using gsub in awk but it didnt work..

awk -F "|" '{for (i=1;i<=NF; i++) gsub($i,/^[ \t]+|[ \t]+$/+" ",""); {print$0}}' xyz.dat

can some correct me if I am wrong some where??

[/SSW/oracle]vi orgfile

xxx | 2007-02-28 | 2007-02-28 | | | 1
xxx | 2007-02-28 | 2007-02-28 | | | 2

Hi,

Thanks for your response.. but the problem is i have millions of records in the file and one more thing is there are lot of files like that. so it would be good if i have some command so that i can write a script...

Also there is address field where it should not trim that spaces in between....

ex
i/p

xxx | 2007-02-28 | 2007-02-28 | | | 1 | meyer singapore
xxx | 2007-02-28 | 2007-02-28 | | | 2 | meyer singapore

o/p

xxx|2007-02-28|2007-02-28|||1|meyer singapore
xxx|2007-02-28|2007-02-28|||2|meyer singapore


So only left and right spaces should be trimmed..

how can I achieve this??

Not quite the required solution, but good to remember...
dev>>cat orgfile            
xxx | 2007-02-28 | 2007-02-28 | | | 1 | meyer singapore
xxx | 2007-02-28 | 2007-02-28 | | | 2 | meyer singapore
dev>>cat orgfile | tr -d " "

Hi
Thanks for that.. I did some modification for your command taking care of the first string and last string with spaces..

And the one which can be used to remove the spaces in left and right of the delimeter including first and last string with spaces is

sed 's/| */|/g;s/ *|/|/g;s/^[ \t]*//;s/[ /t]*$//' orgfile

Thanks a lot for your help
