‘m working in Ubuntu bash terminal application and remotely on a RHEL server in cloud platform. I typed the wrong and dangerous command. I no longer wish to remember dangerous command in the history file. How can I remove or delete a single command from bash history file?
often type the wrong command as follows under Linux bash shell:
rsync -av dir1 [email protected]:/path/to/dir1
cp -av file1*.txt file2*.txt /path/to/dest
I need to correct those command as follows:
rsync -av dir5 [email protected]:/path/to/dir1
cp -av delta1*.txt delta2*.txt /path/to/dest
How do I replace dir1 with dir5 or file with delta and repeat the last command under bash shell?
