echo不换行

echo的参数中, -e表示开启转义,这样就可以使用\t等字符

[yangl@ln01 cuffdiff]$ echo -e "we are family"
we are family
[yangl@ln01 cuffdiff]$ echo -e "we are fami\tly"
we are fami ly                                      #\t被转义成制表符

开启 -e 后行末使用 \c 表示不换行

[yangl@ln01 cuffdiff]$ echo -e "we are family\c"
we are family[yangl@ln01 cuffdiff]$                 #没换行
[yangl@ln01 cuffdiff]$ echo -e "we are fami\cly"
we are fami[yangl@ln01 cuffdiff]$                   #没换行，并且\c后面的字符未被打印
[yangl@ln01 cuffdiff]$
