Bash: Assigning variables

[sjau]

Hiya

I have a little code snippet like this:

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:

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...

[falko]

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:

#!/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.

grep bla /path/to/example.txt

, but not with URLs, like

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

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

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