UNIX for Dummies Questions & Answers

HI, guys, I am having some problem with the echo command, so I want to echo some text to a file name loginFile, the result inside the loginFile should looks like:

Code:

expect ">"

so what I did is:

Code:

echo "expect "">"""  >> $loginFile

but it just gave out:

Code:

expect >

The thing is I still need the double quote the start and the end of the echo since there are lines which I need to use variable, such as:

Code:

echo "send ""cd $destDir""" >>$loginFile

ANd because of the reason I cannot use the single quote as well

Just to sum up, I need something that looks like:

Code:

echo "[content]" >> $loginFile

and can generate out the result above.
Thank you very much for your help really appreciate it

Try

Code:

$ echo 'expect ">"'

expect ">"

$ echo "expect \">\""

expect ">"

if you want to print the double quotes also in the file then just put a \ in front of the quotes you want to print.
double quotes are used to specify string and considered as a special character. if u are printing like this

Code:

echo "expect "">"""  >> $loginFile

then it takes 3 strings enclosed in 3 pair of double quotes

Code:

1) "expect "
2) ">"
3) ""

hence you are getting the result as expect >
if you want to remove the special meaning of any metacharacter , put a \ before that chatracter.

Code:

echo "expect \">\""  >> $loginFile
