Shell Programming and Scripting

I have this line in a file

gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/port7[4gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/0] = gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/port7[4gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/0];
gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/np_ing0_head[9gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/0] = gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/np_ing0_head[9gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/0];

I want output to be

gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/port7[4:0] = gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/port7[4:0];
gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/np_ing0_head[9:0] = gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/np_ing0_head[9:0];

Code:

> echo "xyz[123abc456]" | sed "s/\[[0-9]/&:/" | sed "s/[0-9]\]/:&/" | cut -d":" -f1,3
xyz[1:6]

> echo "do re me xyz[123abc456]" | sed "s/\[[0-9]/&:/" | sed "s/[0-9]\]/:&/" | cut -d":" -f1,3
do re me xyz[1:6]

Now that we all know what you want, what have you tried so far and where are you stuck?

I tried It does only for the part which is on leht hand side of = sign . But needed it on the right hand side of = sign

cat filename | sed "s/\[[0-9]/&:/" | sed "s/[0-9]\]/:&/" | cut -d":" -f1,3


Result is
gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/np_ing0_head[9:0] = gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/np_ing0_head[9gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/0];

Code:

echo "$invalue" | sed "s/\[[0-9]/&:/g" | sed "s/[0-9]\]/:&/g" | cut -d":" -f1,3,5
gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/port7[4:0] = gtgti1/gtgticcrunit1/gtgti_ccrunit_10n/port_arbiter1/port7[4:0];

nawk -f pitagi.awk myFile

pitagi.awk:

Code:

BEGIN {
  FS="[[]|[]]"
}
{
  for(i=1; i<=NF; i+=2)
     if (i==NF)
       print $NF
     else
       printf("%s[%d:%d]", $i, substr($(i+1),1,1), substr($(i+1), length($(i+1))-1))
}

thanks a lot .. BTW, I am trying to understand 1, 3 and 5. I did man on cut and see it says output only those fileds. considering this, last : is 4th filed , it should be 1,3 and 4 is it not ? I may be wrong


help me to understand this.
