☆ busybox で cat -n

Coreutilsが入っていないらしい環境で。

$ awk

Usage: awk [OPTION]... [program-text] [FILE ...]
 
Options:

$ ls -alF `which cat`
lrwxrwxrwx    1 admin    administ         7 Oct 31 18:10 /bin/cat -> busybox*
$ cat -n .bash_profile 
cat: invalid option -- n
BusyBox v1.01 (2014.09.01-18:02+0000) multi-call binary
 
Usage: cat [-u] [FILE]...
 
Concatenates FILE(s) and prints them to stdout.

$ alias catn="awk '{print NR, \"\t\", \$0}' $1" 
$ alias catn
catn='awk '\''{print NR, "\t", $0}'\'' '

$ catn  .bash_profile  
1 	 # .bash_profile

13 	 if [ -f ~/.bashrc ]; then

15 	 fi

エスケープややこし。
なんか足りない気がするが、とりあえずこれで。
