Question

i am inside a directory called TestJ. Inside this directory i have many folders like MSC1,MSC2 … MSC19, HLR1,HLR2 .. ,SGSN1,SGSN2 .. .Now inside each of these directories is a script ALARMS.sh. What i want to do is loop through all these folders and execute ALARMS.sh in each folder . what my present code does is use this

ls -d SGSN* > temp.txt
while read sgsn_line;do
    echo $sgsn_line
    cd $sgsn_line
    ALARMS.sh
    cd ..
done < temp.txt

ls -d HLR* > temp.txt
while read hlr_line;do
    echo $hlr_line
    cd $hlr_line
    ALARMS.sh
    cd ..
done < temp.txt

ls -d MSC* > temp.txt
while read msc_line;do
    echo $msc_line
    cd $msc_line
    ALARMS.sh
    cd ..
done < temp.txt
rm temp.txt 

But i want to do the same job without listing the folders in any file. like for example we can loop through files in a given folder using for file in *.txt. I would like to be able to do the same for folders(only folders).

Use like below…

for sgsn_line in `ls -ltr SGSN* | grep ^d | awk '{print $NF}'`;do
    echo $sgsn_line
    cd $sgsn_line
    ALARMS.sh
    cd ..
done
