& is the pattern space. \& is the character "&". \ is called "escape" it means take the next character literally not as a special character or a metacharacter.


sed /%26/\&/g'

is what it...

That's not correct, I suggest you try what I posted instead.

You're just allocating pointers. A pointer to nothing can't hold anything. You need to allocate memory for them to point to, too,...

sed '

awk 'NR<=4' infile

awk 'NR==2' infile

$ ruby -ne '(print and exit) if $.==2 ' file

If you have to stick with /bin/sh, you could use /dev/random as discussed here: Random Number with /bin/sh - Linux / UNIX Forum (http://nixcraft.com/shell-scripting/14861-random-number-bin-sh.html)...

sed '5!d' infile

awk (nawk on solaris)example: When the statement between ' and ' evaluates to true, the fifth line has just been input, it means print this line, the default awk action.

# awk
awk 'NR==5'...

Hi, I meant the closing / actually ;). Have you discovered the "[code] tags" button already?

Oh, he wanted spaces, well, some enhancements are left to the student! I guess our look and post cycles crossed, so like a pair of bad script processes! :D

Hi, DGPickett, you probably mean:
sed 's/\(.*\),/\1 it /'
nice.

sed 's/\(.*\),/\1it/'

My sed may not always be as terse as the awk from awk gurus, but you might figure out what it does and how it does it more easily. The wild card .* is a greedy spring...

sed 's/,/STUFF/5'

Echoes the number of characters in var
echo ${#var}

Neat /bin/bash solution frans, here is one with /bin/sh
#!/bin/sh
i=1
LEN=$( echo $1 | wc -c )
while [ $i -lt $LEN ]
do
ARRAY[$i]="$( echo $1 | cut -c$i )"
let i=i+1
done
echo Element...

Suppose you had a CSV file you wanted to be a table. Ignoring quotes and quoted commas for the moment (Access 2000 does, so why not me?), this would turn it into table guts:

sed '
...

$ dos2unix file
$ tr -d '\r' < file
$ ruby -i.bak -pne 'gsub("\r","")' file

Your data file is messed up. Run the following command and then run grep.


dos2unix your_file your_file


If you do not have "dos2unix" in your system, try "dos2ux".
Otherwise, you could try...

Just a hunch, but check if there are any funky characters in your data file.


od -bc your_file

Your grep looks broken. What OS and grep version are you using ?

$ echo $s
#
$ cat $a
stanle#y hey
tc#p ss#h
udp tcp
PDB CDB
$ grep "$s" $a
stanle#y hey
tc#p ss#h
$ grep -c "$s" $a
