UNIX for Dummies Questions & Answers

i ran into another road block after more data:

S10000000146981+0000003113079+0000000096981+123456789
S10000000150030+0000003113079+0000000050003+123456789
S10000000190040+0000003113079+0000000050004+123456789

awk '{print substr($0,1,2)substr($0,31,13)substr($0,16,15)"0000000000000"}' file1 > file2

file2 looks like this. i am loosing my +123456789

S10000000096981+0000003113079+0000000000000
S10000000050003+0000003113079+0000000000000
S10000000050004+0000003113079+0000000000000

i tried to replace position 552-565 with 524-537, but nothing changed. does awk have chars limitation ?

can this be done in sed instead of awk ?

again, thank you much.

Hi.

Awk does have a limitation, but it's higher than 565. It's usually between 2560 and 4096 bytes.

Gawk, nawk and other, newer awks don't (or shouldn't) have this limitation.

When you say you tried something, and it didn't work, if often helps if you show how you did it.

You're losing the +1234... bit because you never printed it.

Code:

awk -v FS="+" '{print substr($0,1,2)substr($0,31,13)substr($0,16,15)"0000000000000" FS $NF}' file1

S10000000050003+0000003113079+0000000000000+123456789
S10000000050004+0000003113079+0000000000000+123456789

Just dawned that you asked a question about sed limitations earlier. Are you using Minix, or Linux?! ;-)

i feel so dumb for asking something that i could not understand (awk).

awk '{print substr($0,1,2)substr($0,552,13)substr($0,524,15)"0000000000000"}' file1 > file2

i am on aix5.3 flavor.

i am going to try my best to understand your awk code.
