How to insert a custom string into the result of the Linux paste command
I know that the Linux command paste can be used to merge two lines in two files. My question is how to add some other strings to it?
For example I have 2 files:
[[email protected] ~]# cat c1
aaaa
bbbbbbbbbbbbb
[[email protected] ~]# cat c2
11111111
222222222222
[[email protected] ~]#
[[email protected] ~]# paste c1 c2
aaaa 11111111
bbbbbbbbbbbbb 222222222222
[[email protected] ~]#
How to insert text between them, for example, how to get the following result?
var aaaa = some_function(11111111);
var bbbbbbbbbbbbb = some_function(222222222222);
Can this be achieved with the paste command? Thank you.
Solution
Maybe there’s a way to do it with paste, but it’s certainly easy to do with awk :
paste c1 c2 | awk '{ printf("var %s = some_function(%s);\n", $1, $2); }'
