Shell Programming and Scripting

Hi All,

I am using following script to name the file base of some values

Code:

#!/bin/sh
sourcefile=$1
awk '
BEGIN{ n = 1; name = "FILEFILE12" n ".txt"; }
{
if (substr($0,1,10) == "FILEFILE12") 
{
close (name)
n++
a = substr($0,11,10);
b = substr($0,21,5);
name = b "_Src_" a ".txt"

}
print > name
}
' $sourcefile

Values in a and b are coming with spaces and hence the file which is forming is like "test1 _Src_test2 .txt" .

Can you please help me in trimming the spaces.

Please use next time code tags for your code and data

Remove extra spaces by below trick
Say
l

Code:

ampm="a  b  c"
lampms=${lampm//[[:space:]]}
echo $lampms
abc

How to use code tags

Code:

tr -d [:SPACE:]

is the simplest solution for this

You just need to tweak the substr function parameters to avoid the space. Provide the input file you are using so that we can also have a look.

I know.. but.. above for simple understand ... as per que asked ..

Note: SPACE here always have to be in lower case .... [:space:]

# a="a b c"
# echo $a | tr -d [:SPACE:]
tr: invalid character class `SPACE'

Also
# echo $a | tr -d [:space:]
b c <-- Missing 1st char ...

# echo $a | tr -d "[:space:]" <-- Must be quoted
abc

There are multiple ways ... using sed, awk, tr etc...

Else:

Code:

pandeeswaran@ubuntu:~$ echo a b c|tr -d [[:space:]]
abc

my data is coming as

INDIAINDIABACD 11 XYZ
INDIAINDIABACD 12 XYZ


and i split the data into multiple files based in INDIAINDIA and file name will be BACD_11.txt and BACD_12.txt but in this case it is forming as "BACD _Src_12 .txt" and "BACD _Src_11 .txt"

a = substr($0,11,10)
a2=gsub(/[ \t]+$/, "", a)
b = substr($0,21,5)
b2=gsub(/[ \t]+$/, "", b)
fn = a2 "_Src" b2 ".txt"

using gusb i am not able to trim also it is returning blank to a2 and b2 respectively.

This whole code is inside awk
