I tried this below seems not working

Hello arunkumar_mca,

Could you please try following and do let me know if this helps you.
Code:
awk -F";" '/11095/{for(i=1;i<=NF;i++){if($i ~ /-[0-9]+/){sub("-","",$i)}}} 1'  OFS=";"  Input_file

Thanks,
R. Singh

The negative appears to be in field #10, change that if I cannot count correctly.
Code:
awk -F ';'  ' $1==11095 {$10=$10 * -1} {print} ' infile> outfile

Verify outfile then rename it.

To add to Jim's approach, you need to specify the OFS as well:
Code:
awk -F ';'  -v OFS=';' '....

Hmm. Using scrutinizer's change, I got onto a different UNIX real flavor - this works correctly, note the addition of sprintf:

Code:
 awk -F ';' -v OFS=";"  ' $1==11095 {$10=sprintf("%0.2f",$10 * -1)} {print} ' myfile

If you are sure you don't want ANY negatives, try
Code:
awk 'gsub(/-/, _)+1' myfile

or
Code:
sed 's/-//g' myfile

There is of course tr .
Assuming the file structure remains the same as is shown.
Code:
tr -d "-" < /path/to/infile > /path/to/outfile
