how to get all the shell env value?

llobak

Hi,

 I know that we can read the shell env value by using getShellEnvVar("XYZ"). If i want to know ALL the shell env value, how can i do it with SKILL?   

 

Regards,

SL

  • Hi SL

    Please refer to COS solution 1843362. There is no single cmd to do it. One possible method is to first dump the output of a system("env") cmd in a file and then re-read the file.


    Best regards

  • procedure( allEnvVars()
    let( (i v time line)
    v = makeTable("v" nil) ; create an association table to hold all the shell variables and their values
    time = stringToTime(getCurrentTime()) ; get current time as number
    if(system(sprintf(nil "env > /tmp/%n" time)) == 0 then ; run env command
    if(i = infile(sprintf(nil "/tmp/%n" time)) then ; open temp file containing output from env command
    while(gets(line i) ; loop through output of env command
    line = parseString(line "= ")
    if(length(line) > 0 then
    ;v[car(line)] = cadr(line) ; get env var's value from "env" output
    v[car(line)] = getShellEnvVar(car(line)) ; get env var's value using skill
    )
    )
    close(i)
    else
    printf("error when opening temp file ")
    )
    else
    printf("error while running env ")
    )
    deleteFile(sprintf(nil "/tmp/%n" time))
    v
    )
    )

  •  Thanks for the help from both of you. Actually i've already tried the method before, but I'm facing some problem as some of the env value that i can get from getShellEnvVar() command, I could not get it in unix by typing env. Can anyone enlight me why is it so? Thanks in advance.

  • Maybe the environment variables are being set by:

    a) the virtuoso/icfb command wrapper
    b) the virtuoso/icfb executable itself (or even some SKILL code)
    c) some wrapper command you use to launch virtuoso/icfb

    If you launch env from within icfb, it should inherit anything that icfb is seeing.
