Shell Programming and Scripting

Dear Rakeshawasthi,

I tried the below code in Bash shell, but i am getting error as "syntax error near unexpected token '$'do\r'' .

kindly clarify.....


Code used:

test=testfile
count=1
for i in `awk '{FS="[{}= \t]+";print $1}' $test`
do
a=`grep -w $i $test | awk '{FS="[{}= \t]+";for (i=2;i<=NF;i++)print $i}' | xargs`
if [[ $i == "rule" && $count -ne 1 ]];then
break
fi
echo $i $a
(( count = $count + 1 ))
done



Thanks in advance

Dear panyam,

i have used the below code, which you referred....

awk -F"[{=}]" '!($1 in A) {key[++key[0]]=$1} {a[$1]=a[$1]" "$2;next} END { for(i=1;i<=key[0]/2;i++){ print key[i] a[key[i]]}}' | sed '/^[ ]*$/d' input_file.txt


I am getting the output, same as input. It is working just like cat command.

Kindly clarify......
Vasanth

sorry there was a typo .

Code:

awk -F"[{=}]" '!($1 in a) {key[++key[0]]=$1} {a[$1]=a[$1]" "$2;next} END { for(i=1;i<=key[0];i++){ print key[i] a[key[i]]}}' input_file_name.txt |  sed '/^[ ]*$/d'

Yes, thanks a lot, Panyam....

It works for me.
have you replaced the testfile with your input file name..
tell me how can I replicate the error?

One more thing, panyan i need a scritp to remove the space before and after the operator like( +, -, ||, &&).

Ex :

Input file

apple + manago

mango && fresh + apple fresh || fruit


Desired output:

apple+manago

mango&&fresh+apple fresh||fruit


Note: betwee the desired operator space should be removed, between words do not remove space.

Thanks in advance,
Vasanth

Dear rakeshawasthi ,

I have used cygwin bash shell.

I think your code, u r executing in KSH.


code used :

test=testfile
count=1
for i in `awk '{FS="[{}= \t]+";print $1}' $test`
do
a=`grep -w $i $test | awk '{FS="[{}= \t]+";for (i=2;i<=NF;i++)print $i}' | xargs`
if [[ $i == "rule" && $count -ne 1 ]];then
break
fi
echo $i $a
(( count = $count + 1 ))
done


Error message:
syntax error near unexpected token '$'do\r''

Thanks
