Changing a forward slash to another character in bash
If you find yourself needing to replace a forward slash character, for instance, in a path, with another character, you can use the code snippet below.
This script replaces a forward slash with an underscore in a hard coded string:
new_var=$(echo "/path/to/directory" | sed -e 's/\//_/g')This script replaces a forward slash with an underscore in an argument passed into a function or into a script:
new_var=$(echo $1 | sed -e 's/\//_/g')This script replaces a forward slash with an underscore in a previously defined variable.
new_var=$(echo $orig_var | sed -e 's/\//_/g')To replace the underscore with something different, change ‘s/\//_/g’ to replace the underscore with something else. For example, to instead use a dash, use ‘s/\//-/g’
Like so:
new_var=$(echo $orig_var | sed -e 's/\//-/g')
