I'm running in a simple problem, cannot export a string value with hyphens in bash variables. Here is what's happening:
.env
NAME_0=`Bruno - Souto`
NAME_1="Bruno - Souto"
NAME_2='Bruno - Souto'
export.sh
#!/bin/bash
set -xv
export $(cat .env | egrep -v "(^#.*|^$)" | xargs)
echo ${NAME_0}
echo ${NAME_1}
echo ${NAME_2}
output:
dev@dev:~/teste$ ./export.sh
export $(cat .env | egrep -v "(^#.*|^$)" | xargs)
++ cat .env
++ xargs
++ egrep -v '(^#.*|^$)'
+ export 'NAME_0=`Bruno' - 'Souto`' NAME_1=Bruno - Souto NAME_2=Bruno - Souto
+ NAME_0='`Bruno'
./export.sh: line 4: export: `-': not a valid identifier
./export.sh: line 4: export: `Souto`': not a valid identifier
+ NAME_1=Bruno
./export.sh: line 4: export: `-': not a valid identifier
+ NAME_2=Bruno
./export.sh: line 4: export: `-': not a valid identifier
echo ${NAME_0}
+ echo '`Bruno'
`Bruno
echo ${NAME_1}
+ echo Bruno
Bruno
echo ${NAME_2}
+ echo Bruno
Bruno
I DO NEED to export with 'xxx - xxx', doesn't matter how. Any ideas?

First assignment ( NAME_0
) is invalid since the backticks imply that you want to run a command Bruno
with arguments -
and Souto
.
Not sure why you don't just source
the file and then manually export
the variables (you already know the names - per the echo
calls - so go ahead and export
, too), eg:
$ source .env
-bash: Bruno: command not found # result of using backticks in the NAME_0 assigment
$ typeset -p NAME_0 NAME_1 NAME_2
declare -- NAME_0=""
declare -- NAME_1="Bruno - Souto"
declare -- NAME_2="Bruno - Souto"
$ export NAME_0 NAME_1 NAME_2
$ typeset -p NAME_0 NAME_1 NAME_2
declare -x NAME_0=""
declare -x NAME_1="Bruno - Souto"
declare -x NAME_2="Bruno - Souto"
NOTE: NAME_0
is empty due to the use of backticks in .env
With a single liner.. I would skip the quotes in your .env
file and read into your bash script with export
..
.env
NAME_0=Bruno - Souto
NAME_1=Bruno - Foo
NAME_2=Bruno - Bar
test.sh
#!/bin/bash
while read -r line; do LANG=C export "$line"; done <".env$1"
echo $NAME_0
echo $NAME_1
echo $NAME_2
output
$ bash test.sh
Bruno - Souto
Bruno - Foo
Bruno - Bar
CLI
~$ while read -r line; do LANG=C export "$line"; done <".env$1"
~$ echo $NAME_0
Bruno - Souto
~$ echo $NAME_1
Bruno - Foo
~$ echo $NAME_2
Bruno - Bar
