Bash: Assigning variables

Hiya

I have a little code snippet like this:

Code:

LINK=`/bin/grep -f http://www.spamcop.net/sc?id= $FILENAME`
echo $LINK
LINK=`/bin/fgrep http://www.spamcop.net/sc?id= $FILENAME`
echo $LINK
LINK=`/bin/ls $FILENAME`
echo $LINK

The output is this:

Code:

grep: http://www.spamcop.net/sc?id=: No such file or directory

/bin/fgrep: line 2: exec: grep: not found

1147891663.9720_2.t390.greatnet.de:2,ST
grep: http://www.spamcop.net/sc?id=: No such file or directory

/bin/fgrep: line 2: exec: grep: not found

1147896741.16696_2.t390.greatnet.de:2,ST

Why do grep and fgrep not work but the ls does?

 

I don't think you can use grep for files that aren't on the same system.

 

They are on the same system but I have to use grep -F and not grep -f ^^

But I still wonder why fgrep does not work...

 

But you can't use grep with URLs, no matter if they point to the same system.

 

Not sure what you mean. The shell script looks like this now:

Code:

#!/bin/bash

# ENTER PATH OF THE VERIFICATION EMAILS FROM SPAMCOP
PATH="/home/mail/web4p1/Maildir/.Spamcop-Reply/cur"

# ENTER WEBPATH TO PHP SCRIPT
URL="http://www.roleplayer.org/spamcop.php"

cd $PATH

for FILENAME in *S
do

        LINK=`/bin/grep -F http://www.spamcop.net/sc?id= $FILENAME`
        echo $LINK
#        LINK=`/bin/fgrep http://www.spamcop.net/sc?id= $FILENAME`
#        echo $LINK
#       LINK=`/bin/ls $FILENAME`
#       echo $LINK
#       lynx -dump $URL?link=$LINK


#       /bin/rm $FILENAME

done

 

You can use grep with local files, e.g.

Code:

grep bla /path/to/example.txt

, but not with URLs, like

Code:

grep bla http://www.example.com/example.txt

 

You could use wget to download the file then pipe it into grep.

Code:

wget -q -O - "http://www.example.com/example.txt" | grep bla
