Comma replaced by a point

Scripting Forums AppleScript | Mac OS X

Hello,

From the Terminal the command:

sysctl vm.swapusage | awk '{print $7}'

returns: 7,00M

but from a script,

do shell script "sysctl vm.swapusage | awk '{print $7}'"

returns: 7.00M

Why? How to keep the comma?

Thanks.

The short answer to “why” is that do shell script inherits a different environment. The longer answer is here:

Thanks Shane. I knew this file but I don’t found the solution inside.

but I found that:

set swapusageused to do shell script "sysctl vm.swapusage | awk '{print $7}'"
convertPointToComma(swapusageused)

on convertPointToComma(numberAsText)
	set o to offset of "." in numberAsText
	if o = 0 then return numberAsText
	tell numberAsText to return text 1 thru (o - 1) & "," & text (o + 1) thru -1
end convertPointToComma

Or you could tell the command to respect your locale:

do shell script "LANG=fr_FR sysctl vm.swapusage | awk '{print $7}'"

A crude way to use the decimal point character set on the user’s machine:

set swapusageused to do shell script "sysctl vm.swapusage | awk '{print $7}' | sed 'y/0.0/" & 0.0 & "/'"

An awk expert would no doubt do the sed bit with awk too. The entire edit with sed might look like this:

set swapusageused to do shell script "sysctl vm.swapusage | sed -E 's/^([^ ]+ +){6}| .*$//g ; y/0.0/" & 0.0 & "/'"

Edit: Code shortened.

Maybe Joel may use :

use AppleScript version "2.4" # requires at least Yosemite
use scripting additions
use framework "Foundation"

set thisLocale to current application's NSLocale's currentLocale()
set theLocalIdentifier to thisLocale's localeIdentifier as text --> "fr_FR"
do shell script "LANG=" & theLocalIdentifier & " sysctl vm.swapusage | awk '{print $7}'"

Hello,

For older System, I use this, which runs with any decimal separator

set decimSep to character 2 of ((1 / 2) as text)

set swapUsage to do shell script " sysctl vm.swapusage | awk '{print $7}'"

set swapUsage to do shell script ("echo " & swapUsage & " | tr '.' '" & decimSep & "'")
