am 23.12.2007 13:21:56 von apogeusistemas
Hi:
I need remove all days from $a variable finded in $b variable, and I
create
this script, but I=B4m having errors...
a=3D"2 3 9 10 16 17 23 24 30 31"
b=3D"1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
26 27 28 29 30 31"
for day in `echo $a`
do
c=3D`echo $b | tr -d $day`
done
echo $c
/script
2 4 5 6 7 8 9 0 2 4 5 6 7 8 9 20 2 22 2 24 25 26 27 28 29 0
What could I modify to get this script working good ?
Thank You.

For example:

b="1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 \
28 29 30 31"
for day in $a; do
b=`echo "$b" | sed -e "s/\([ ^]\)$day\([ $]\)/\1\2/g"`
done
echo "$b" | tr -s ' '

Your script seems to be trying to do the opposite of what you say, so I'm=
not
sure what you really want, but maybe this will give you an idea:
$ a=3D"2 3 9 10 16 17 23 24 30 31"
$ b=3D"1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 =
26 27
29 30 31"
$ A=3D`echo "$a" | tr ' ' '\n'`
$ B=3D`echo "$b" | tr ' ' '\n'`
$ C=3D`comm -13 <(echo "$A") <(echo "$B")`
$ c=3D`echo $C`
$ echo "$c"
1 4 5 6 7 8 11 12 13 14 15 18 19 20 21 22 25 26 27 28 29
man comm for details.

One could move the tr pipes into the process substitution brackets.
Or - since we use shells that already support process substitution -
even use parameter expansion instead of tr; e.g. in ksh93 or bash3...
C=$( comm -13 <(echo "${a// /$'\n'}") <(echo "${b// /$'\n'}") )

Yeah, I know it could be reduced to:
$ a=3D"2 3 9 10 16 17 23 24 30 31"
$ b=3D"1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 =
26 27 29
30 31"
$ c=3D`comm -13 <(echo "$A" |tr ' ' '\n') <(echo "$B" |tr ' ' '\n') |tr '=
\n' ' '`
$ echo "$c"
1 4 5 6 7 8 11 12 13 14 15 18 19 20 21 22 25 26 27 29
but I was shooting for clarity....

You need to re-word your requirements. What you need is to delete the
days from the $b variable not found in the $a variable.
What you wrote is days in $a not to be found in $b, which are none,
since every element of $a variable is present in $b.
### strip any newlines in the $a variable & pad with spaces.
aa=3D" `echo $a` "; # Note: $a variable deliberately left unquoted.
bNOTa=3D
for day in $b; do
case $aa in
*\ "$day"\ * ) :;;
*) bNOTa=3D${bNOTa}${bNOTa:+' '}${day};;

php:
$a = array(2,3,9,10,16,17,23,24,30,31);
$b = range(1,31);
$r = array_diff($a, $b);

Change the last line (for example) to:
printf("%s\n", implode(' ', array_diff($b, $a)));
or one of the other bazillions php string/array manipulation methods...

You didn't show $a starting as a string, not
an array. What are those silly semicolons for?
Even awk doesn't need semicolons. And this
doesn't produce any output.
a = "2 3 9 10 16 17 23 24 30 31"
puts ( (1..31).to_a - a.split.map{|s| s.to_i} ).join(" ")
a = %w(2 3 9 10 16 17 23 24 30 31)
puts ( (1..31).to_a - a.map{|s| s.to_i} ).join(" ")
a = [2,3,9,10,16,17,23,24,30,31]
puts ( (1..31).to_a - a ).join(" ")
a = 2,3,9,10,16,17,23,24,30,31
puts ( (1..31).to_a - a ).join(' ')
a = 2,3,9,10,16,17,23,24,30,31
puts ( [*(1..31)] - a ).join(' ')

Please pardon my prolixity.
a = 2,3,9,10,16,17,23,24,30,31
puts ( [*1..31] - a ).join(' ')

Not really difficult:
$a = explode(' ', "2 3 9 10 16 17 23 24 30 31");
> What are those silly semicolons for?
It's called "syntax". php statements must be terminated by semicolons.
> Even awk doesn't need semicolons.
Well, in case you don't know, perl, c and a great deal of other languages
do.

See my other reply; the last line had to be different.

Isn't it supposed to be rude to put the words
'syntax' and 'Perl' in the same post ;D)
Happy new year! (and that's being proactive at removing days)
