help in modification of code
I have below code, i want to run this code, but this below code should run on


Code:
myblocka
myblockb
myblockcc

myblockanything

but it will not run on "myblock"

Code:
for BLOCK in /sys/block/myblock*
do
        echo "100000" > "$BLOCK"/abcd

done


Note: This below code block line should not run on myblock while run as above.

do
       echo "123"> "$BLOCK"

done

Hi Guru,

Try if directory name contains special character or number in it...
This script won't work here...

Code:
myblock_new
myblock9

Will above code run on below? Only characters are there no special characters and no numbers are there.

/sys/block/myblockaa
/sys/block/myblockbb
/sys/block/myblockdc
/sys/block/myblockabcd

Same if i use for another code, is below line correct?

Code:
 for BLOCK in /dev/myblock[a-z]

Why don't you try it out for yourself with something like:
Code:
for BLOCK in /sys/block/myblock[a-z]*
do
  echo "$BLOCK"
done

for BLOCK in $(ls /sys/block/myblock* | grep -v '^/sys/block/myblock $')
