Bash And Exclusions in a List

Just a quick snippet on doing exclusions when you loop through a list.

1
DIRS=`ls -l --time-style="long-iso" $MYDIR | egrep '^d' | awk '{print $8}'`
2
EXCLUDELIST="mail Mail"
3

4
for EXCLUDE in $EXCLUDELIST
5
do
6
    DIRS=`echo $DIRS | sed "s/\b$EXCLUDE\b//g"`
7
done
8

9
for DIR in $DIRS
10
do
11
    echo  ${DIR} :
12
done

For some reason on Solaris sed had an issue with “\b” so I adjusted to sed “s/$EXCLUDE//g”. Shown as follow:

1
#Linux:
2
$ echo "d1 d2 d3" | sed "s/\bd2\b//g"
3
d1  d3
4

5
# Solaris Fails:
6
# echo "d1 d2 d3" | sed "s/\bd2\b//g"
7
d1 d2 d3
8

9
# Solaris Works
10
# echo "d1 d2 d3" | sed "s/d2//g"
11
d1  d3
