Question Assigne an expression to a variable

I hope this is not a duplicate thread, but i didn't find anything similar...

I had this script:
Code:
filename1=/swkgr/bin/risk/GF2KGR/arch/GF2KGR_M_
filename2=/swkgr/bin/risk/GF2KGR/arch/GF2KGR_D_
day='date +%m%d'
echo $filename1$day
echo $filename2$day

and i want this output:
Code:
/swkgr/bin/risk/GF2KGR/arch/GF2KGR_M_1015
/swkgr/bin/risk/GF2KGR/arch/GF2KGR_D_1015

(Path + timestamp)

But I have
Code:
/swkgr/bin/risk/GF2KGR/arch/GF2KGR_M_date +%m%
d
 
/swkgr/bin/risk/GF2KGR/arch/GF2KGR_D_date +%m%
d

(Path + instruction as string).

Where the error is? Smilie

But for me it doesn't work, with or without space after of before $ (or any character, I tried anything).

Anyone has another solution?

try this

Code:
day=‘date +%m%d‘

The quotes are wrong. Try
Code:
day=`date +%m%d`

What shell are you using. The $() construct is for ksh/bash.
