Thanks guys,

Not sure if it's the best solution, but in the end I chose to create another nested function to run the awk command:

function csvdiff() {
function _csvdiff() {
awk '
...

Hi guys,

I wrote the following function to compare two csv files column by column.
However, sometimes the input needs to be sorted before parsing it to awk.

I can do this by changing the awk...

Thanks! Works great

Hi all,

I'm trying to read in a character and use it as a separater on a string:

#!/bin/ksh

echo "Enter input line"
read input_header

echo "Enter separator:"
read separator

Thanks, the client is not a problem as it works from another system running Solaris (this one is Red Hat). I just found out about the mailx -a option which also attaches files. I guess I'll use this.

Hi,

I'm trying to send mail with attachments using uuencode, but it doesn't work.

Command (also tried with mailx):
uuencode testfile testfile | mail emailadress

The email I get doesn't...

Hi all,

I need to do a grep in a specific file inside multiple (tar.gz) archives.

I know zgrep can grep in an archive, but as far as I know, I can't supply a specific filename from inside the...

Another way to do it in awk:
awk '/Mamma/ { s=x ; getline ; next } s { print s } { s=$0 } END { print s }' file

Give this a try:
awk '{x=substr($0,10,10); gsub(/\|/," ",x); print substr($0,0,10), x, substr($0,20)}' OFS="" file

Try this:
awk '/---/{p++;next} p==2' file

You can't put variables in the shebang. You could use the following depending on if you have the right bash path in your $PATHvariable:
#!/usr/bin/env bash

Hi wisecracker, I think I understand the OPs request quite clearly the way he described it. And although you make a valid point, I consider it as a data entry issue which I think is out of scope here.

This should fix it:

sed -e :a -e "s/\([^,]\)\"\([^,]\)/\1'\2/g;ta" file

Try this instead:
sed "s/\([^,]\)\"\([^,]\)/\1'\2/g" file

I don't understand the commotion, a simple sed would suffice, no?

$ sed 's/\([^,]\)\"\([^,]\)/\1\x27\2/g' file...

You can use SSH to execute commands remotely, have a look at the manual. You'll need to use either expect or sshpass to parse the password. In any case, it's always better to connect using an ssh-key.

Thanks Jim, although it's not exactly what I was looking for.

I know the awk, tac and rev solutions but was especially interested in getting a good sed example for educational purposes as it was...

Hi guys,

I'm wondering what the best way would be to reverse words in a string based on certain characters.

For example:
echo Word1Word2Word3Word4 | sed '
/\n/ !G
...

Which OS and version of sed do you use?

You could try this:
find . -type f -iname *.ics -exec sed -i '/^DT\(START\|END\)/s/[0-9][0-9]$/00/;s/\r//' {} \;

Try this and make sure you have a backup of all your files:
find . -type f -iname *.ics -exec sed -i -e '/^DT\(START\|END\)/s/[0-9][0-9]$/00/' -e 's/\r//' {} \;

if the carriage return is not...

try something like this:

print glob.glob("abc.*")

Using grep, assuming that the timestamp is 12+ characters, and there are no other 12+ digit numbers in the filename:
echo test.input.20130501010101.txt | grep -o '[0-9]\{12,\}*'

Try this:

tcpdump -i eth1 icmp[0] =8 >output.txt &
sleep 60; kill $!

Don't look for a literal ^M, instead look for the special character which you can obtain by pressing 'ctrl-v+m'

Have a look at the man pages;
