Bash Script to run commands from the history
I wrote a tiny bash_script to be able to run commands from history with entering the number of the history line:
Search term with grep in the history, display and print to file with tee:
history | grep -i "search-term" | tee "$HOME/.hg.temp"
Then select the appropriate line by its number with grep, reduce it to the command with awk and run the command.
run=$(grep "line-number" "$HOME/.hg.temp" | awk -F' ' '{print $2}'); $run
this works fine, but if I put it all into a bash-script it won't work anymore:
#!/bin/bash
if [ "$1" = "-e" ] || [ "$1" = "--enter" ]; then
run=$(grep "$2" "$HOME/.hg.temp" | awk -F' ' '{print $2}')
$run
exit
fi
history | grep -i "$1" | tee "$HOME/.hg.temp"
for some reason grep does not find any match and the $HOME/.hg.temp file is always empty. What am I missing out here?
