Hello All,

I am trying to clean all color control characters from log file. I am able to clean all other control characters except ^[(B . Please help me to clean this control character also.

I am using these combination to clean control characters.

cat $LOGFILE | sed -e 's/\x1b\[[0-9;]*m//g' > $LOGDIR/Temp.txt

Thanks
Amit

Here's a quick (and slightly dirty) variant in sed:

Code:

echo "^[(B" | sed 's/\^\[.B//'

Best,
HMW

I got best solution so far to remove any control characters.

sed -e 's/\x1b$\[[0-9;]*m\|(B$//g'

I tested and it worked perfect.
