SRC_FILE=$1
BKP_FILE=$2
echo "SRC_FILE :" ${SRC_FILE}
echo "BKP_FILE :" ${BKP_FILE}
In the above code how can I give the direct path to SRC_FILE and BKP_FILE. like if I want to give the path say, "app/retro/power/shell" to SRC_FILE and "app/retro/power/script" to BKP_FILE.
How do I fit the above path to the script??
You should just pass the argument when calling your script.
SRC_FILE=$1 BKP_FILE=$2
echo "SRC_FILE :" ${SRC_FILE}
echo "BKP_FILE :" ${BKP_FILE}
So the PATH for SRC_FILE and BKP_FILE should be passed like this :
./script.sh SRC_FILE BKP_FILE
EDIT:
If you want to write down the PATH directly into the code you would set the variables as follows:
SRC_FILE="app/retro/power/shell" BKP_FILE="app/retro/power/script"
echo "SRC_FILE :" ${SRC_FILE}
echo "BKP_FILE :" ${BKP_FILE}

Background
I am running a Jenkns Job, called Job A, that feeds its build parameters into a perl script, called ScriptA.pl, in the following format below:
#Check the input params
my $PARAM1 = $ENV{ "PARAM1" };
my $PARAM2 = $ENV{ "PARAM2" };
.....more params fed in the same way
if ( $PARAM1 eq "" ) {
print "PARAM1 is a required parameter.\n";
exit 1;
}
if ( $PARAM2 eq "" ) {
print "PARAM2 is a required parameter.\n";
exit 1;
}
.....more param checks done in the same way
###Script then runs a bunch of execution statements####
Problem
I am trying to run this script from Linux command line in cshell in the following way to test that the execution component works:
/% ScriptA.pl jetFuel steelBeams
And it thinks that no parameters have been entered, since this error is returned
PARAM1 is a required parameter.
Question
How do I properly input Jenkins parameters into a Jenkins script from command line?
If you can't modify the Perl script so it reads command-line parameters (which would improve its general usability to boot), maybe create a simple wrapper script:
#/bin/sh
env PARAM1="$1" PARAM2="$2" perl ScriptA.pl
(Yes, sh. Nobody should use csh for anything in 2019.)
OK so im trying to get exec() to execute a script that works fine from idle.
If I try a simple script it works fine, such as:
hello = "hello"
world = "world"
print hello + " " + world
But the script I actually want to run wont work and I can only assume its because of the module import, the code is as follows:
import serial
port = serial.Serial('/dev/ttyAMA0', baudrate=19200, bytesize=8, parity=serial.PARITY_NONE, stopbits=1, timeout=5)
port.open
port.write("\x02\x00\x00\x00\x00\x02")
My PHP code is:
<?php
$result = exec('python python.py');#This works fine
echo $result
?>
<?php
$result1 = exec('python proOn.py');# This wont work
echo $result1
?>
Try this:
<?php
$command = escapeshellcmd('proOn.py');
$result1 = shell_exec($command);
echo $result1;
?>
refer this.
I have a PHP if/else statement. This is the code I'm trying to echo under an else condition.
<?php $locked = ForumData::is_topic_locked($post->topic_id);
if ($locked->topic_locked == 1) {echo '<td align="right"><font color="#FF0000">Topic Locked</font><td>';}
else {
echo '<td align="left"><img src="<?php echo SITE_URL?>/lib/skins/flyeuro/images/forums/t_reply.gif"/></td>'; }
?>
The bit I'm interested to echo is this.
<img src="<?php echo SITE_URL?>
If I try this... 'echo SITE_URL'
Parse error: syntax error, unexpected T_ECHO, expecting ',' or ';'
But this doesn't parse the image, and if I try parsing anything else, it's giving me parsing errors, which I can't fix?
How can I therefore produce an echo inside another echo?
why did you open a <?php tag again, you are already in echo line?
echo '<td align="left"><img src="'.SITE_URL.'/lib/skins/flyeuro/images/forums/t_reply.gif"/></td>';
and what is SITE_URL? Is that a variable, did you forget to put $?
echo prints out the string that you gave as parameter,
echo "foo";
As #hakre mentioned about it, . is used to concatenate strings.
$var = "foo"."bar"; //foobar
So you can use it in echo line,
$var = "foo"."bar"; //foobar
echo "foo "."bar ".$var // foo bar foobar
And It's not important weather variable defined as a string. It would be a constant variable.
define('SITE_URL', 'localhost:8080/phpvms');
echo "my website URL is ".SITE_URL; //my website URL is localhost:8080/phpvms
Remember:
<?php echo "View"; ?>
" and \
this!
Hope that's enough of a hint!#
Your problem is probably solved this way:
echo '<td align="left"><a href="',
url('Forum/create_new_post?topic_id=' . $post->topic_id . '&forum_id=' . $post->forum_id . '') ,
'"><img src="', SITE_URL,
#######################
'/lib/skins/flyeuro/images/forums/t_reply.gif"/></a></td>';
In PHP you can use constants quite like variables, e.g. to output them. You don't need to stack echoes inside each other or something.
I am having trouble with checkboxes. What I am doing is displaying a list of checkboxes, if previously checked they will show the check mark, then you submit them and another php should recognize which were checked and which weren't. My script works fine for boxes previously unchecked, if you check them the action php recognizes it, but for boxes already checked I get Notice - undefined variable - for the boxes (even if unchecked/checked again). I really can't seem to find my way around this.
My code is
$ind=0; //counting variable
//generating checkboxes from an xml
foreach($xml as $checkbox)
{
$checks=$xml->checkbox[$ind]->active; //the active tag has a 0 or 1 stored.
echo "Activate ".$ind; // shows activate 0, activate 1, etc...
echo "<form name='checkb' action='show.php' method='post'>
echo "<input type='checkbox' name='checks[]' class='act' value='".$ind."'";
if($checks==0){ echo ">";} else{echo " checked ='checked'>";}
echo "<input type='hidden' name='ind' value=".$ind.">";
$ind=$ind+1;
echo "<input type='submit' name='sub' value='Submit'/> </form>"; }
On my action php I have
$chks = $_POST['checks'];
$N = count($chks);
echo("Active checkboxes ");
for($i=0; $i < $N; $i++)
{
echo($chks[$i] . " ");}
All this worked well until I decided to show if the boxes had been previously checked. So I guess the question is, why won't php recognize checked=checked as a true value? Or is there any other way to do this?
Thanks!
Seems like a lot of issues here.
Why are you outputting a form for each checkbox?
Where is your submit for the form?
You need a space in front of checked='checked' where you echo it out - echo " checked='checked'>"
If you move form output out of the loop, you will need to add your incremented value to the hidden input name property as well (or make it an array like checks, otherwise you will
only get one value for the field.
My attempt to try and clean it up a little.
$ind = 0;
echo "<form name='checkb' action='show.php' method='post'>";
foreach($xml as $checkbox){
echo "Activate $ind";
echo "<input type='checkbox' name='checks[]' class='act' value='$ind' ".(($checks == 0) ? " />" : " checked='checked' />";
echo "<input type='hidden' name='ind_$ind' value='$ind' />";
$ind++
}
echo "</form>";
Notice, like Mike said before that checked='checked' has the space before so that there is seperation between components. Also, your hidden elements all had the same names, so I added the $ind quantifier.
Hope this helps.
I have a main script that I am running. What it does is read through a directory filled with other powershell scripts, dot includes them all and runs a predefined method in each made up of the first portion of the dot delimited file name. Example:
Run master.ps1
Master.ps1 dot sources .\resource\sub.ps1
Sub.ps1 has defined a function called 'dosub'
Master.ps1 runs 'dosub' using Invoke-Expression
Also defined in sub.ps1 is the function 'saysomething'. Implemented in'dosub' is a call to 'saysomething'.
My problem is I keep getting the error:
The term 'saysomething' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the
name, or if a path was included, verify that the path is correct and
try again.
Why can't the method 'dosub' find the method 'saysomething' which is defined in the same file?
master.ps1:
$handlersDir = "handlers"
$handlers = #(Get-ChildItem $handlersDir)
foreach ( $handler in $handlers ) {
. .\$handlersDir\$handler
$fnParts = $handler.Name.split(".")
$exp = "do" + $fnParts[0]
Invoke-Expression $exp
}
sub.ps1:
function saysomething() {
Write-Host "I'm here to say something!"
}
function dosub() {
saysomething
Write-Host "In dosub!"
}
Your code works on my system. However you can simplify it a bit:
$handlersDir = "handlers"
$handlers = #(Get-ChildItem $handlersDir)
foreach ( $handler in $handlers )
{
. .\$handlersDir\$handler
$exp = "do" + $handler.BaseName
Write-Host "Calling $exp"
& $exp
}
Note the availability of the BaseName property. You also don't need to use Invoke-Expression. You can just call the named command ysing the call (&) operator.
What you have given works as needed. You probably don't have the directories etc proper on your machine. Or you are running something else and posting a different ( working!) code here.
You can also make following corrections:
. .\$handlersDir\$handler
instead of above you can do:
. $handler.fullname
Instead the splitting of the filename you can do:
$exp = "do" + $handler.basename
