I need to remove a particular line in a file crontab ex:

* * * * * root /home/linaro/funcao1.sh
* * * * * root /home/linaro/funcao3.sh
* * * * * root /home/linaro/funcao4.sh
* * * * * root /home/linaro/funcao5.sh

would like to delete the line

* * * * * root /home/linaro/funcao4.sh

Remembering that this file is not in crontab it will be imported according to the script

tried to use the sed but my deficiency in regular expressions did not allow me to make it work

sed '* * * * * root /home/linaro/funcao4.sh' /home/linaro/mycron.txt
linux bash sed

Could use grep in the form:

grep -v "* * * * * root /home/linaro/funcao4.sh" /etc/crontab > /home/usuario/mycron
mv /home/usuario/mycron > /etc/crontab

Use sed -i to replace in the file itself:

sed -i '/* * * * * root \/home\/linaro\/funcao4.sh/d' arquivo

I managed to solve ^^

sed '/* * * * * root \/home\/linaro\/funcao4.sh/d' /etc/crontab  > /home/linaro/mycron
cat /home/linaro/mycron > /etc/crontab
rm -rf mycron
