BASH question

cxel91a · 12-31-2003, 01:47 AM

How can I redirect this information into a file at the command line?
df -h | awk '/\/dev\/hda3/ {print $5}'

I tried single quotes: echo 'df -h | awk '/\/dev\/hda3/ {print $5}' ' > bashscript
didn't work.

I tried double quotes: $echo "`df -h | awk '/\/dev\/hda3/ {print $5}' "> bashscript
didn't work

This is what I get for the file content. No options under man echo worked.

df -h | awk //dev/hda3/ {print }

you need the "right" single quote... and here it is --> `

Tried that to. It will only put the output into the file.

Huh? I was reading this and thinking that's what you wanted. And fatgod's right:

Code:

echo `df -h | awk '/\/dev\/hda6/ {print $5}'` > foo

What do you want? The literal command in a file?

I want to get the commands typed on the command line into the file. Not the output of the command.

If I understand what you're saying I have to wonder why not type them into the file directly?

What was the problem? The '$5' disappearing? This seems to work:

Code:

echo "df -h | awk '/\/dev\/hda3/ {print \$5}'" > foo

thanks, for some strange reason I was getting 2 // before dev.
