for loop - How to create a correct array with ls? -


i know can use array=( $( ls . ) ) have next problem code:

array=( $( ls ./cos/cos*.txt ) ) ((  = 0 ;  <= ${#array[*]}-1;  i++  ))     sed 's/$'"/`echo \\\r`/" ${array[$i]} > ./cos/temp.txt     mv ./cos/temp.txt ${array[$i]} done

i have more loops in whole script differents directories respective instructions of sed , mv no problems, have problem part of code, appears command ls saving entire result in first possition of array, i.e. if cos directory has cos1.txt, cos2.txt , cos3.txt, instead of saving cos1.txt in ${array[0]}, cos2.txt in ${array[1]} , cos3.txt in ${array[2]} saving:

cos1.txt cos2.txt cos3.txt in ${array[0]}, entire list in possition 0 of array. know wrong?

it's not clear actual problem is, should write code this:

# don't use ls. let glob expand list of files array=( ./cos/cos*.txt ) # don't iterate on array indices; iterate on items fname in "${array[@]}"; do     # trying add carriage return end of each line?     sed "s/\$/$'\r'/" "$fname" > ./cos/temp.txt     mv ./cos/temp.txt "$fname" done

you don't need array; can put glob in loop:

for fname in ./cos/cos*.txt;    ... done

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
