There's a syntax error in awk if else statement which I got the code from another question and unable to fix it.
Bash one-liner code to output unique values.
Can someone correct the statement.
awk 'BEGIN {output=0} /Slave_IO_Running.*No/ {output+=1} /Slave_SQL_Running.*No/ {output +=2} END {if(output==3} {print 0} else {if(output==0} {print 3} else {print output}}'
debug output
awk 'BEGIN {output=0} /Slave_IO_Running.*No/ {output+=1} /Slave_SQL_Running.*No/ {output +=2} END {if(output==3}{print 0} else {if(output==0} {print 3} else {print output}}'

if(output==0} and if(output==3} should end with close paren ), not close brace }.
You should use else if for nested if statements, and those braces are only necessary for multiple operations.
END {if(output==3) print 0; else if(output==0) print 3; else print output}
Just for fun:
END {print output==3? 0: output==0? 3: output}
There are clues in the error messages, e.g.:
awk: cmd. line:1: ... END {if(output==3}{print 0} else {if(output==0} {print 3} else {print output}}
awk: cmd. line:1: ^ syntax error
It really couldn't be much clearer.
I'm trying to call a variable which contains a percentage sign in it, but when I do I receive the following error. Even when only trying to create it, it errors. When I exclude it, my script works fine, but I want it to print this variable value in the 3rd field.
awk -v postutil="$postutil"

I ended up just using sed to remove the percent sign and then re-added it in the awk statement.
I have two files - FileA and FileB. FileA will be changed. FileB contains the new values. FileB has 3 fields. The first two fields will be compared with FileA's first two fields. If the fields match, Field3 should be changed. The code below is working in this manner: "If the two values match, change field3 and print the line. If there is no match, next." The behavior I want is, "If there is no match, print the line unchanged." The "else" part of the code is not working and I've tried so many variations.
awk -F'\t' -v OFS='\t' '
# first, read in data from file B
NR == FNR { values[$1 FS $2] = $3; next }
# then, output modified lines from matching lines in file A
($1 FS $2) in values { $3 = values[$1 FS $2]; print } else { print $0 }

Your syntax is off. Check the tag info for some learning resources.
In any case, you don't need an else as such. You can conditionally set $3 to the new value (as you already are doing), and then always print the line (which may have been modified or not).
Here we use the shortcut 1 to always print the line. 1 is an always-true pattern that invokes the default action, which is to print the current line. If that doesn't make sense now, it will soon.
$ awk 'BEGIN {FS=OFS="\t"}
NR == FNR {values[$1 FS $2] = $3; next}
($1 FS $2) in values {$3 = values[$1 FS $2]}1' fileB fileA

I am trying to use awk to remove the lines in file that do not match the digits after the NM_ but before the . in $2 of list. Thank you :).
file
204 NM_003852 chr7 + 138145078 138270332 138145293
204 NM_015905 chr7 + 138145078 138270332 138145293
list
TRIM24 NM_015905.2
awk
awk -v OFS="\t" '{ sub(/\r/, "") } ; NR==FNR { N=$2 ; sub(/\..*/, "", $2); A[$2]=N; next } ; $2 in A { $2=A[$2] } 1' list file > out
current output
204 NM_003852 chr7 + 138145078 138270332 138145293
204 NM_015905.2 chr7 + 138145078 138270332 138145293
desired output (line 1 removed as that is the line that does not match)
204 NM_015905.2 chr7 + 138145078 138270332 138145293
awk 'NR==FNR{split($2,f2,".");a[f2[1]];next} $2 in a' list file
$ awk -F'[ .]' 'NR==FNR{a[$2];next}$2 in a' list file

I have File1
A,B,C
and File2
D,E,F
I am trying to have
AD, AE, AF, BD, BE, BF, CD, CE, CF
unsuccessfully by
echo {`cat File1`}{`cat File2`}
giving
{A,B,C}{D,E,F}
How can you solve the problem by Zsh/AWK?
awk -F, '
NR==FNR {
# read lines from File1 into the array f1
f1[NR]=$0
next
}
{
# foreach line in File2
split(f1[FNR], words); # get words from corresponding line in File1
sep = ""
for (i in words) {
for (j=1; j<=NF; j++) {
printf("%s%s%s", sep, words[i], $j)
sep = ", "
}
}
print ""
}
' File1 File2
If File1 contains
A,B,C
1,2,3
and File2 contains
D,E,F
4,5,6
then the awk script outputs
AD, AE, AF, BD, BE, BF, CD, CE, CF
14, 15, 16, 24, 25, 26, 34, 35, 36
I don't know zsh, here's what I did with bash and sed:
echo "A,B,C" >a
echo "D,E,F" >b
for i in `cat a | sed -e "s#,#\n#g"`;
do for j in `cat b | sed -e "s#,#\n#g"`;
do echo -n "$i$j, ";
done ;
done | sed -e "s#,\s\$##"
The output then is:
AD, AE, AF, BD, BE, BF, CD, CE, CF
