Using sed to replace a character before another character in a line
0
I try to use sed or whatever to replace a number of a line /opt/tin/toss to become a *
For example
37 7 * * * /opt/tin/toss
43 7 * * * /opt/tin/te1
58 7 * * * /opt/tin/test2
Output:
37 * * * * /opt/tin/toss
43 7 * * * /opt/tin/te1
58 7 * * * /opt/tin/test2
Normally, 7 generates randomly, It can be 2, 4 or 8, running from 0-24.
Could anyone please help me? Thank you.
