Years ago, maybe 2011 based on the age of files, our Systems group moved our Linux home directories to a central system. My only real complaint about this move was finding anything I needed in my Bash history. See, I am terrible at remembering things and often make typos. It is easier to go back in my history to a prior command and either run it or modify that one and run. The same home directory across all these systems complicated things by co-mingling commands. I was able to find\u00c2\u00a0things. Just eventually. That\u00c2\u00a0seemed inefficient.<\/p>\n
Eventually, this situation annoyed me to the point I decided to fix it. And the fix was so simple it is amazing that I did not immediately address it rather than suffering with it for a couple years. (Well, actually, we picked Desire2Learn before the change so 90% of my server responsibilities were on Windows. Only when I was promoted to a Technology Strategist and returned\u00c2\u00a0to majority work in Linux did it get annoying enough to address.)<\/p>\n
The fix? Add hostname to the HISTFILE variable\u00c2\u00a0in .bash_profile.<\/p>\n
export HISTFILE=”${HOME}\/.bash_history.`hostname`”<\/p><\/blockquote>\n
Apparently I made the change back on December 18th. In the six months since, I have not noticed any oddities with the history.\u00c2\u00a0This morning I noticed that I have about twenty different host named history files of various sizes and dates.<\/p>\n
Given the number of files, while writing this post, I decided to\u00c2\u00a0re-organize these into a directory. (An organized home directory is a happy home directory. Heh.)<\/p>\n
export HISTFILE=”${HOME}\/.bash_history\/.bash_history.`hostname`”<\/p><\/blockquote>\n
Then I ran these.<\/p>\n
mv .bash_history .bash_history.org
\nmkdir\u00c2\u00a0.bash_history
\nmv .bash_history.* .bash_history<\/p><\/blockquote>\nThen I exited which dumped that session’s history into a file in the old location. I logged in again and used cat and the output redirect to append those new lines to the correct file in the new location.<\/p>\n
Exited again and logged in again. And everything still looks good.<\/p>\n","protected":false},"excerpt":{"rendered":"
