So i have all these words in a text file:



dfasdfasdf
adsgad
fghjast
hdasfh
adfhadfn


And i have to display the number of chars of the smallest word without using the 'awk' and 'sed' commands...
I have tried all variants of wc but it works with the full text file and not only line per line.






shell awk sed grep wc

    What do you mean by smallest? The shortest? Can you use sort?

  • Yes, the shortest one. I have used sort but it only sorts me the words by alphabetical order.

  • mapfile -t arr < yourtextfile; for f in "$arr[@]"; do printf '%sn' "$#f"; done | sort -n |head -n1 or using the read as follows: while read -r line; do printf '%sn' "$#line"; done < fff | sort -n | head -n1

Using parameter expansion, you can get the length of a variable contents:



$#variable


Just read the file line by line and remember the shortest word:



while read word ; do
 : $shortest:=$word
 if [ $#word -lt $#shortest ] ; then
 shortest=$word
 fi
done < "$1"
echo "$shortest"

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
