Ok, lets clear a few things up. Thx davidl......heres the test results Smilie

echo abcdef | sed -e "s/c/X/" <--should yield--> abXdef
that worked, it printed abXdef, like u said Smilie

ls -ld filename |cut -c2-10 <--Should yield--> -rwxr-xr-x
yep, worked excellent Smilie

ls -ld somefilename | cut -c2-10 | /usr/bin/tr [-rwx] [0421]
didnt work, printed error message: /usr/bin/tr Bad string. BUT this worked:
ls -ld filenmame | cut -c2-10 | tr '\-rwx' 0421
which printed converted the r's, w's, and x's with numbers e.g 421000000

BUT, I couldn't get any further and get it to print the numerically values with spaces????

Makaveli.2003, try this... Basically the same stuff you've been doing... with a small change in syntax.

echo abcdef |sed 's/cd/GREAT/g' <--Should Display--> abGREATef

echo abcdef |sed 's/./& /g' <Should Display--> a b c d e f
***Be careful when you type this one!!
***Note there are no spaces from 's/./&
and there is ONE space after '&'****

You've probably already looked at that.. just though I'd throw it out anyways Smilie

ls -l menu | cut -c2-10 | tr '\-rwx' 0421 | sed "s/./& /g" | awk '{print $1+$2+$3 $4+$5+$6 $7+$8+$9}'
produces: 7

got it to work, think it was coz i didnt put the space between the "&" and the "/", sorrrrryyyyyy. But shouldnt it print "700"????

The code you just showed should indeed output 3 digits. Make sure that you are executing the code as shown. In earlier posts, you erroneously showed the awk portion as:

awk '{print $1+$2+$3+$4+$5+$6+$7+$8+$9}'
which prints a single sum, instead of
awk '{print $1+$2+$3 $4+$5+$6 $7+$8+$9}'
which prints three sums.

Spaces and punctuation are critical. Once, a missing period in a Fortran program caused a major unmanned rocket launch to crash (really).

First leave off the awk part and try this:

ls -l menu | cut -c2-10 | tr '\-rwx' 0421 | sed "s/./& /g"

That should print 4 2 1 0 0 0 0 0 0

You're welcome, Makaveli. And I hate to add to an already too-long thread, but, I don't like posting a solution that will sometimes give incorrect results. So, I offer my new solution, which should handle all cases including suid and sticky bits. And special thanks to Perderabo for his excellent contribution.

ls -ld $* | awk 'BEGIN {
v["r1"]=400; v["w2"]=200; v["x3"]=100; v["s3"]=4100; v["S3"]=4000
v["r4"]=40 ; v["w5"]=20 ; v["x6"]=10 ; v["s6"]=2010; v["S6"]=2000
v["r7"]=4  ; v["w8"]=2  ; v["x9"]=1  ; v["t9"]=1001; v["T9"]=1000}
 for (i=1;i<=9;i++) val=val+v[substr($0,i+1,1)i]
 printf "%4d %s\n",val,$NF}' jb*

when you tried echo piped into tr, did you put a single quote around the tests? ie...

echo rwx | tr '[rwx] [421]'

I tried exactly what was posted and received the error no match when I didn't use the single quote, but it worked fine when I used the single quote.
