Write to File, but Overwrite It If It Exists

In Bash, if you have set noclobber a la set -o noclobber, then you use the syntax >|

For example:

echo "some text" >| existing_file

This also works if the file doesn't exist yet

• Check if noclobber is set with: set -o | grep noclobber

• For a more detailed explanation on this special type of operator, see this post

• For a more exhaustive list of redirection operators, refer to this post

Despite NylonSmile's answer, which is "sort of" correct.. I was unable to overwrite files, in this manner..

echo "i know about Pipes, girlfriend" > thatAnswer

zsh: file exists: thatAnswer

to solve my issues.. I had to use... >!, á la..

[[ $FORCE_IT == 'YES' ]] && echo "$@" >! "$X" || echo "$@" > "$X"

Obviously, be careful with this...

If your environment doesn't allow overwriting with >, use pipe | and tee instead as follows:

echo "text" | tee 'Users/Name/Desktop/TheAccount.txt'

Note this will also print to the stdout. In case this is unwanted, you can redirect the output to /dev/null as follows:

echo "text" | tee 'Users/Name/Desktop/TheAccount.txt' > /dev/null

#!/bin/bash

cat <<EOF > SampleFile

Put Some text here 
Put some text here
Put some text here

EOF

Just noting that if you wish to redirect both stderr and stdout to a file while you have noclobber set (i.e. set -o noclobber), you can use the code:

cmd >| file.txt 2>&1

More information about this can be seen at .

Also this answer's @TuBui's question on the answer @BrDaHa provided above at Aug 9 '18 at 9:34.

To overwrite one file's content to another file you use the single greater than sign, using two will append.

echo  "this is foo" > foobar.txt
cat foobar.txt
    > this is foo

echo "this is bar" > foobar.txt
cat foobar.txt
    > this is bar
    

echo "this is foo, again" >> foobar.txt
cat foobar.txt
    > this is bar
    > this is foo, again
    

As mentioned in other answers, if you have noclobber set then use the >| operator.
