Can someone explain what the second half of this script does? (second line)
$self is defined elsewhere... (I know what that part does, Just wondering what the action=~... is all about/)
$action = "http://example.com/test.php";
$action = $self->{url} . ($action =~ /^\// ? "" : "/" ) . $action;
It returns an empty string if $action starts with a slash, and a slash if it does not start with a slash.

I am using Powershell and I have a variable like this:
$E = "Apple"
When I run $E[0] I expect to see Apple, but it shows A only. How can I do that?
$E = "Apple" Is not an array, it is a simple string declaration so when you try to get index 0 of that string (or char array) you are returning the first character in the character array:
0 1 2 3 4
[A] [P] [P] [L] [E]
The define an array you need a second item (separated by a comma):
$E = "Apple", "Orange"
Then you can use $E[0] to return Apple like you are wanting.

Hi i try to transcript an awk command to powershell
i have a text file
SQLBefore:=
UPDATE SYSADM.PS_S1_R_FLWUP
SET S1_FLWUP_DATE_CHK=SYSTIMESTAMP
, S1_FLWUP_DATE_LAST=NULL
WHERE S1_FLWUP_NAME='GGGGG_ETAT_JJ'
SQLAfter:=
UPDATE SYSADM.PS_S1_R_FLWUP
SET S1_FLWUP_DATE_LAST=SYSTIMESTAMP
, S1_FLWUP_STAT_SID=1
WHERE S1_FLWUP_NAME='TTTTT_ETAT_'
SQLFailed:=
UPDATE SYSADM.PS_S1_R_FLWUP
SET S1_FLWUP_DATE_LAST=S1_FLWUP_DATE_FRST
, S1_FLWUP_STAT_SID=3
WHERE S1_FLWUP_NAME='JJJJ_ETAT_JJJ'
And i would like to do the same than this unix command in powershell
cat $this_file|awk '/SQLAfter/,/SQLFailed/ {print $0}'| grep -v SQL|sed -e 's/^$//'
It's return
UPDATE SYSADM.PS_S1_R_FLWUP
SET S1_FLWUP_DATE_CHK=SYSTIMESTAMP
, S1_FLWUP_DATE_LAST=NULL
WHERE S1_FLWUP_NAME='GGGGG_ETAT_JJ'
I'm getting stuck to do the delimiter like awk, between "SQLBefore:=" and "SQLAfter:=" with powershell
Thanks for your help.
I'm a beginner of powershell sorry for my english
One possibility, assuming I'm reading the question correctly (however "bad" you think your English might be I assure you it's considerably better than my AWK).
((get-content testfile.txt -raw) -split 'SQL(?:Before|After):=')[1]

How can I detect and show an error if someone put a letter and the program expects a number?
A regexp match makes this easy. Searching for any character which isn't a numeral or an arithmetic symbol:
if ( $input =~ /[^0-9+*/-]/ ) {
print "Incorrect character detected!\n"
}
Literally anything which is a letter:
if ( $input =~ /[A-Za-z]/ ) {
print "Incorrect character detected!\n"
}

I have an array in the third element dataArr[2], I know it contains a 10 digit phone. I need to only read or print the first 6 digits. For instance if my phone is 8329001111, I need to print out the 832900. I tried to see if I can use substr but I keep reading or printing the full list. Do I need to dereference..
Try this :
$dataArr[2] =~ s/\s//g; # ensure there's no spaces
print substr($dataArr[2], 0, 6);
# ^ ^ ^
# variable | |
# offset start|
# |
# substring length
