How to store w3m dump result into a variable in a bash script? The result I got by w3m dump is
C: randomIP randomPORT randomUSERNAME randomPASSWORD
I want to cut "C:" and store everything else into variables so I can add it into a file.

You can store any bash command output in this manner:-

var=$(command) # replace command by w3m dump command
#Later you can replace first occurring of C: by sed
var=$(echo $var | sed s/^C://)

Now var variable will consist of dump without "C:".

  • Now I have only the text I want, but how to assign randomIP randomPORT randomUSERNAME randomPASSWORD to variables? Thanks! – Albert Karlsson Mar 23 '16 at 15:01
  • I got it to work with IFS=" " set $var echo $1 echo $2 echo $3 echo $4 – Albert Karlsson Mar 23 '16 at 15:13
  • yeah you can `cut` command to separate a line. You can use some thing like this:- `echo 'randomIP randomPORT randomUSERNAME randomPASSWORD' | cut -d' ' f1` for getting `randomIP`. Similarly `f2` for 2nd argument and so on. – Devavrata Mar 24 '16 at 10:40

<your command> | read useless var1 var2 var3 var4

As explained in man read, read will (big surprise!) read a line on standard input (hence the pipe) and assign the given variables one by one using the IFS (by default the space character) as a delimiter in the input.

So in your example, useless will be assigned to "C:"; var1 to "randomIP"; ...

  • Quite true. Besides, I realize that my here string was pointless here, a pipe will suffice. I added some explanations but my solution is straightforward now. Thanks. – Julien Lopez Mar 23 '16 at 12:36
