I have a file from Wild Wild Web and it contains malformed UTF8. I handled malformed UTF8 in my other codes in previous versions of Raku. In 2020.10 version, I am running into this issue below. Has the support for utf8-c8 changed (this page says it should work, but it doesn't seem to) :
https://docs.raku.org/language/unicode#index-entry-UTF-8_Clean-8
This page has this example:
say slurp($test-file, enc => 'utf8-c8');
Now my code on the command line:
raku -e 'my $a = slurp("zlist"); for $a.lines { .say }'
Malformed UTF-8 near bytes 73 e2 5f at line 55 col 14
in block <unit> at -e line 1
Then using this:
raku -e 'my $a = slurp("zlist", enc => 'utf8-c8'); for $a.lines { .say }'
===SORRY!=== Error while compiling -e
Undeclared routine:
utf8-c8 used at line 1
My code is simple and essentially copied from the example. What am I doing wrong?

I have the following simple bash code to test string comparison:
#!/bin/sh
BRANCH="master"
echo $ref
if [[ "$ref" = "refs/heads/$BRANCH" ]]
then
echo "Matches"
else
echo "Do not match"
fi
When I ran the code using export ref=/refs/heads/master && . sample I get the following result:
/refs/heads/master
Do not match
What may be causing the problem?
What is causing the problem is the missing slash in your test: /refs/heads/master is not equal to refs/heads/master!

I have this ruby program to parse a CSV file. I am missing a endif somewhere and I cannot figure out.
require 'csv'
prevrow=nil
newarray=Array.new
CSV.foreach("\\\\192.168.0.1\\fe18cb0618cabd41\\ninjatrader\\uniqueside.csv", col_sep: ',') do |row|
if(prevrow==nil)
# do nothing
newarray<<row
prevrow=row
elsif (prevrow!=nil and row[0]!=prevrow[0] )
# do something
newarray<<row
prevrow=row
##count=1
elsif(prevrow!=nil and row[0]=prevrow[0] and ##count<4)
puts "new date"
newarray<<row
prevrow=row
##count++
end
end
removesamedirctiontop4.rb:23: syntax error, unexpected keyword_else
removesamedirctiontop4.rb:27: syntax error, unexpected end-of-input, expecting keyword_end
#count++ is not valid ruby. The final "plus" is expecting another parameter and thinks it's on the next line, so the line ends up being interpreted as...
`#count + +end`
So you have an invalid statement and you lose an end.
Change the offending line to
#count += 1

why am I getting "bash missing'" for this:
function get_xserver ()
{
case $TERM in
xterm )
XSERVER=$(who am i | awk '{print $NF}' | tr -d ')''(' )
;;
aterm | rxvt)
# Find some code that works here. ...
;;
esac
}
This is the exact error:
bash: [: missing `]'
The error is not in the code you posted. The error message:
-bash: [: missing `]'
Means exactly what it says - there is a missing ] character, namely in a [ test ] statement.
Try it:
$ [ 1 -eq 2
-bash: [: missing `]'
You need to identify where the error actually is, and add the missing closing bracket.

I'm trying to loop over all environment variables in a shell script, and create an HTML query string from ones which match a pattern. Unfortunately, I can't seem to assign to variables in the loop. I've got this:
#!/bin/sh
IFS=$'\n'
TAGS=""
for item in $(printenv)
do
if [[ $item == FOO_TAG_* ]]
then
TAGS = "${TAGS}&${item}"
fi
done
But this gives me
/etc/script.sh: line 9: TAGS: command not found
/etc/script.sh: line 9: TAGS: command not found
How do I fix this?
In the assignment, remove space between variable name and =
TAGS="${TAGS}${item}"

Using bash, I want to throw away all of the text in a file after the first blank line. The blank line is used as a delimiter between records, and I only want the first record in the file. Unfortunately, the number of lines per record can change depending on what the record refers to exactly, so I can't just keep the first n lines as a global solution.
[EDIT] Here is a solution that works:
qstat -f > out.tmp
grep -A90 -B0 $1 out.tmp > out2.txt
awk '/^$/{exit}{print}' out2.txt
rm out.tmp out2.txt
where $1 points to the name of the text file to be analyzed (passed as an argument to the script that I'm writing). Thanks.
You can do this with pretty much any generic text processing tool, e.g.:
awk '$0==""{exit}{print}'
awk '/^$/{exit}{print}'
sed '/^$/q'
